Rainbow Electronics MAX1329 User Manual

General Description

The MAX1329/MAX1330 are smart data acquisition systems (DASs) based on a successive approximation register (SAR) analog-to-digital converter (ADC). These devices are highly integrated, offering an ADC, digitalto-analog converters (DACs), operational amplifiers (op amps), voltage reference, temperature sensors, and analog switches in the same device.

The MAX1329/MAX1330 offer a single ADC with a reference buffer. The ADC is capable of operating in one of two user-programmable modes. In normal mode, the ADC provides up to 12 bits of resolution at 312ksps. In DSP mode, the ADC provides up to 16 bits of resolution at 1000sps. The ADC accepts one external differential input or two external single-ended inputs as well as inputs from other circuitry on-board. An on-chip programmable gain amplifier (PGA) follows the analog inputs, reducing external circuitry requirements. The PGA gain is adjustable from 1V/V to 8V/V.

The MAX1329/MAX1330 operate from a 1.8V to 3.6V digital power supply. Shutdown and sleep modes are available for power-saving applications. Under normal operation, an internal charge pump boosts the supply voltage for the analog circuitry when the supply is < 2.7V.

The MAX1329/MAX1330 offer four analog programmable I/Os (APIOs) and four digital programmable I/Os (DPIOs). The APIOs can be configured as general-purpose logic inputs and outputs, as a wake-up function, or as a buffer and level shifter for the serial interface to communicate with slave devices powered by the analog supply, AV

. The DPIOs can be configured as generalpurpose logic inputs and outputs as well as inputs to directly control the ADC conversion rate, the analog switches, the loading of the DACs, wake-up, sleep, and shutdown modes, and as an interrupt for when the analog-to-digital conversion is complete.

The MAX1329 includes dual 12-bit force-sense DACs with a programmable reference buffer and one op amp. The MAX1330 provides one 12-bit force-sense DAC with a programmable reference buffer and two op amps. For the MAX1329/MAX1330, a 16-word DAC FIFO can be used with the DACA for direct digital synthesis (DDS) of waveforms.

The 4-wire serial interface is compatible with SPI™, QSPI™, and MICROWIRE™.

Note 1: ADC INL and DNL, offset, and gain are tested at DVDD= 1.8V, AVDD= 2.7V, f

SAMPLE

= 234ksps to guarantee performance

at f

SAMPLE

= 312ksps, DVDD≥ 2.7V and AVDD≥ 5.0V.

Note 2: Guaranteed by design. Not production tested. Note 3: AV

supply current contribution for this module.

Note 4: DNL and INL are measured between code 115 and 4095. Note 5: Temperature sensor accuracy is tested using a 2.5084V reference applied to REFADJ. Note 6: The maximum trip levels for the AV

monitor are 5% below the typical charge-pump output value. The charge-pump output

voltage and the trip thresholds track to prevent tripping at -5% below the typical charge-pump output value.

Note 7: DV

supply current contribution for this module.

Note 8: The normal operation and sleep mode supply currents are measured with no load on DOUT, SCLK idle, and all digital inputs

at DGND or DV

. CLKIO runs in normal mode operation and idle in sleep mode.

NAME FUNCTION

Serial-Data Output. DOUT outputs serial data from the data register. DOUT changes on the falling edge of SCLK and is valid on the rising edge of SCLK. When CS is high, DOUT is high impedance, unless APIO1 is programmed for SPI mode.

Serial-Clock Input. Apply an external serial clock to transfer data to and from the device. When CS is high, SCLK is inactive unless APIO3 is configured for SPI mode. Then the input on SCLK is level-shifted and output at APIO3.

Serial-Data Input. Data on DIN is clocked in on the rising edge of SCLK when CS is low. When CS is high, DIN is inactive unless APIO2 is configured for SPI mode. Then the input on DIN is level-shifted and output at APIO2.

Active-Low Chip-Select Input. Drive CS low to transfer data to and from the device. When CS is high and APIO4 is configured for SPI mode, APIO4 is low.

Open-Drain Reset Output 1. RST1 remains low while DV reprogrammed as a push-pull, active-high, or active-low Status register interrupt output.

Open-Drain Reset Output 2. RST2 remains low while DV reprogrammed as a push-pull, active-high, or active-low Status register interrupt output.

NAME FUNCTION

DAC Internal Reference Buffer Output/DAC External Reference Input. In internal reference mode, REFDAC provides a 1.25V, 2.048V, or 2.5V internal reference buffer output. In external DAC reference buffer mode, disable internal reference buffer. Bypass REFDAC to AGND with a 1µF capacitor.

ADC Internal Reference Buffer Output/ADC External Reference Input. In internal reference mode, REFADC provides a 1.25V, 2.048V, or 2.5V internal reference buffer output. In external ADC reference buffer mode, disable internal reference buffer. Bypass REFADC to AGND with a 1µF capacitor.

Internal Reference Output/Reference Buffer Amplifiers Input. In internal reference mode, bypass REFADJ to AGND with a 0.01µF capacitor. In external reference mode, disable internal reference.

Analog Supply Input. Bypass AVDD to AGND with at least a 0.01µF capacitor. With the

charge pump enabled, see Table 32 for required capacitor values.

Charge-Pump Capacitor Input B. Connect C required capacitor values.

Charge-Pump Capacitor Input A. Connect C required capacitor values.

Digital Supply Input. Bypass DVDD to DGND with at least a 0.01µF capacitor. When using

charge pump, see Table 32 for required capacitor values.

Clock Input/Output. In internal clock mode, enable CLKIO output for external use. In external clock mode, apply a clock signal at CLKIO for the ADC and charge pump.

Exposed Pad. The exposed pad is located on the package bottom and is internally connected to AGND. Connect EP to the analog ground plane. Do not route any PCB traces under the package.
