1 Overview

The ADS7057EVM-PDK evaluation kit includes the ADS7057EVM board and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over USB for data capture and analysis.

The ADS7057EVM board includes the ADS7057 SAR ADC, all the peripheral analog circuits, and the components required to achieve optimum performance from the ADC.

The PHI controller board primarily serves three functions:

• Provide a communication interface from the EVM to the computer through a USB port

• Provide the digital input and output signals necessary to communicate with the ADS7057 device

• Supply power to all active circuitry on the ADS7057EVM board Along with the ADS7057EVM and PHI controller board, this evaluation kit includes an A-to-micro-B USB

cable to connect to a computer.

1.1 ADS7057EVM-PDK Features

The ADS7057EVM-PDK showcases the following features:

• Hardware and software required for diagnostic testing as well as accurate performance evaluation of the ADS7057 ADC

• USB powered — no external power supply is required

• The PHI controller board that provides a convenient communication interface to the ADS7057 ADC over USB 2.0 (or higher) for power delivery as well as digital input and output

• Easy-to-use evaluation software for Microsoft®Windows®7, 64-bit operating systems

Overview

1.2 ADS7057EVM Features

The ADS7057EVM showcases the following features:

• Onboard low-noise, low-distortion ADC input drivers optimized to meet ADC performance

• Onboard ultra-low noise, low-dropout (LDO) regulators, to generate supplies for the operation amplifier and voltage reference to generate the power supply for ADC

2 Analog Interface

The ADS7057 is a low-power, small ADC that supports differential analog inputs. The ADS7057EVM uses a THS4551 fully differential amplifier to drive the inputs of the ADC. The ADS7057EVM is designed for easy interfacing to analog sources. This section describes the front-end driver circuitry details, including jumper configurations for the analog input signal source.

2.1 Connectors for Differential Analog Input

The ADS7057EVM is designed for easy interfacing to an external, analog, differential source through either a subminiature version A (SMA) connectors or 100-mil headers. The ADS7057EVM has two ADS7057 ADCs on board. The ADS7057EVM GUI can either be configured for individual ADC data sampling or simultaneous sampling with both ADCs. Jumpers J1, J2, J7, and J10 are the SMA connectors that allow for differential analog source connectivity through coaxial cables. Alternatively, 100-mil jumper cables or mini-grabbers can be used to connect analog sources to the pin 1 of connectors J3, J6, J8, and J9. Table 2 lists the analog input connectors for the individual ADCs.

2.2 ADC Differential Input Signal Driver

The SAR ADC inputs terminate in switched-capacitor networks that create large instantaneous current loads when the switches are closed, which effectively makes the ADC inputs dynamically low impedance. The differential inputs of the ADC are therefore driven by a THS4551 fully differential amplifier in a small gain configuration to maintain ADC performance with maximum loading at full device throughput of the ADS7057 of 2.5 MSPS.

2.2.1 Input Signal Path

Figure 1 shows the signal path for the positive differential inputs applied to the ADS7057EVM. A separate

THS4551 amplifier is used in a fully differential configuration to drive the differential input of each ADC. An RC filter with values of 10 Ω and 680 pF was selected to achieve a SINAD greater than 79 dB and a THD less than –85 dB for a 2-kHz sine wave input at full throughput of the ADS7057 of 2.5 MSPS.

3 Digital Interfaces

As noted in Section 1, the ADS7057EVM interfaces with the PHI, which in turn communicates with the computer over USB. The three devices on the EVM that the PHI communicates with are the two ADS7057 ADCs (over SPI) and the EEPROM (over I2C). The EEPROM comes preprogrammed with the information required to configure and initialize the ADS7057EVM-PDK platform. When the hardware is initialized, the EEPROM is no longer used.

3.1 SPI for ADC Digital I/O

The ADS7057EVM-PDK supports the interface and calibration modes detailed in ADS7056 Ultra-Low

Power, Ultra-Small Size, 14-Bit, High-Speed SAR ADC. The PHI is capable of operating at a 3.3-V logic

level and is directly connected to the digital I/O lines of the ADC.

4 Power Supplies

The ADS7057 supports a wide range of operation on its analog supplies. The AVDD operates from 2.35 V to 3.6 V. The DVDD operates from 1.65 V to 3.6 V, independent of the AVDD supply. The analog portion of the ADS7057EVM operates from a 5.5-V supply, which in turn generates the 5-V V THS4551 fully differential amplifier using the TPS79901, which is a low-noise, fixed-voltage regulator. The

3.3-V AVDD supply for the ADS7057 is generated using the REF1933 which is a low-drift, low-power,

voltage reference. The TPS79901 regulator can be configured to generate a V

R4 and R8 with appropriate values. Table 3 lists the nearest feedback resistor values that should be populated to generate the desired VDDsupply voltage.

6.1 EVM GUI Global Settings for ADC Control

Figure 9 shows the input parameters of the GUI (as well as their default values), through which the

various functions of the ADS7057EVM-PDK can be exercised. These settings are global and persist across the GUI tools listed in the top left pane (or from one page to another).

ADS7057EVM-PDK Operation

Figure 9. EVM GUI Global Input Parameters

The SCLK Frequency and Sampling Rate are selected on this page. The GUI lets the user enter the target values for these two parameters, and the GUI computes the closest value that can be achieved, considering the timing constraints of the device.

Select either one of the ADCs or both of the ADCs if they are configured in the simultaneous sampling scheme described in Section 2.1 by clicking on the drop-down menu titled Channel Modes. Specify a target SCLK frequency (Hz) and the GUI tries to match this frequency as closely as possible by changing the PHI PLL settings; however, the achievable frequency may differ from the target value entered. Similarly, the sampling rate of the ADC can be adjusted by modifying the Target Sampling Rate argument (Hz). The achievable ADC sampling rate can differ from the target value, depending on the applied SCLK frequency and the closest match achievable is displayed. This page, therefore, allows various settings available on the device to be tested in a repetitive fashion until arriving at the best settings for the corresponding test scenario.

6.2 Time Domain Display Tool

The Time Domain Display tool provides a visualization of the ADC response to a given input signal. This tool is useful for both studying the behavior and debugging any gross problems with the ADC or front-end drive circuits.

The user can trigger a capture of the data of the selected number of samples from the ADS7057EVMPDK, as per the selected interface mode settings using the Capture button as indicated in Figure 10. The sample indices are on the x-axis, and two y-axes show the corresponding output codes as well as the equivalent analog voltages based on the specified reference voltage. Switching pages to any of the analysis tools described in the subsequent sections triggers calculations to be performed on the same set of data.

6.3 Spectral Analysis Tool

The Spectral Analysis tool (see Figure 11) is intended to evaluate the dynamic performance (SNR, THD, SFDR, SINAD, and ENOB) of the ADS7057 SAR ADC through the use of a single-tone, sinusoidal signal FFT analysis, using the 7-term Blackman-Harris window setting. Alternatively, the window setting of None can be used to search for noise spurs over frequency in DC inputs.

For dynamic performance evaluation, the external, single-ended source must have better specifications than the ADC to ensure that the measured system performance is not limited by the performance of the signal source. Therefore, the external reference source must meet the source requirements listed in

Table 6.

6.4 Histogram Analysis Tool

The Histogram Analysis tool can be used to estimate the effective resolution of the ADC due to the performance degradation caused by noise. Effective resolution is an indicator of the number of bits of ADC measurement resolution resulting from performance losses due to noise generated by the various sources connected to the ADC when measuring a DC signal. The cumulative effect of noise coupling to the ADC output (from sources such as the input drive circuits, the reference drive circuit, the ADC power supply, and the ADC itself) is reflected in the standard deviation of the ADC output code histogram obtained by performing multiple conversions of a DC input applied to a given channel.

The histogram corresponding to a DC input is displayed by clicking the Capture button, as Figure 12 shows.

6.5 Offset Calibration

The ADS7057 device can calibrate its own internal offset. The offset calibration can be initiated by the user either on power up or during normal operation. During offset calibration, the analog input pins (AINP and AINM) are disconnected from the sampling stage and connected to an internal reference. The result of the offset calibration is stored in an internal register. For subsequent conversions, the device adjusts the conversion results provided on the SDO output with the value stored in this internal register.

The ADS7057 GUI implements offset calibration, described in the Offset Calibration During Normal Operation section of ADS7056 Ultra-Low Power, Ultra-Small Size, 14-Bit, High-Speed SAR ADC.

Figure 13 shows the Offset Calibration page of the GUI.

ADS7057EVM-PDK Operation

The offset calibration test is conducted regardless of the input signal applied to ADC input pin. Users can keep the ADC input floating or apply a fixed DC voltage to the ADC input. Click the Calibrate button to initiate the internal self-calibration routine on the ADC. The GUI first performs a histogram test for the device as described in Section 6.4 and populates the top graph. The pre-calibrated Mean code is displayed in the Pre Calibration Results box. Next, the SPI calibration frame is sent to the ADS7057 device that enables the internal offset calibration logic. The GUI performs the histogram test for a second time and the bottom graph is populated and the Mean value is displayed in the Post Calibration Results box. Finally, the difference between the first and second mean is displayed in the Offset Correction box.

The computed offset for all subsequent attempts to calibrate the device always yields a result within the limits specified in the data sheet. This indicates that after the calibration is performed for the first time, the offset is actually being applied on all subsequent conversions. This computed offset will remain fixed unless the device is reset or there is a significant change in operating temperature or analog supply voltage.

6.6 Performance Evaluation of ADS7054 Using ADS7057 EVM

The ADS7054 is a slower sampling variant of the ADS7057 (1 MSPS vs 2.5 MSPS). Therefore, the ADS7054 performance can be inferred using the ADS7057 EVM GUI by restricting the Sample Rate(sps)

Target value to no greater than 1M. The performance numbers achieved on the Time Domain Display, Spectral Analysis, and Histogram Analysis pages will be representative of the ADS7054 performance

parameters under similar operating conditions.
