GENERAL DESCRIPTION

The ADR01, ADR02, ADR03, and ADR06 are precision 10.0 V,

5.0 V, 2.5 V, and 3.0 V band gap voltage references featuring high accuracy, high stability, and low power. The parts are housed in tiny, 5-lead SC70 and TSOT packages, as well as in 8-lead SOIC versions. The SOIC versions of the ADR01, ADR02, and ADR03 are drop-in replacements REF02, and REF03. The small footprint and wide operating range make the ADR0x references ideally suited for generalpurpose and space-constrained applications.

to the industry-standard REF01,

The ADR01, ADR02, ADR03, and ADR06 are compact, low drift voltage references that provide an extremely stable output voltage from a wide supply voltage range. They are available in 5-lead SC70 and TSOT packages, and 8-lead SOIC packages with A, B, and C grade selections. All parts are specified over the extended industrial (–40°C to +125°C) temperature range.

Table 1. Selection Guide

Part Number Output Voltage

ADR01 10.0 V ADR02 5.0 V

With an external buffer and a simple resistor network, the TEMP terminal can be used for temperature sensing and

ADR03 2.5 V ADR06 3.0 V

approximation. A TRIM terminal is provided on the devices for fine adjustment of the output voltage.

1

ADRO1, ADR02, and ADR03 are component-level compatible with REF01, REF02, and REF03, respectively. No guarantees for syste-level compatibility are implied. SOIC

versions of ADR01/ADR02/ADR03 are pin-to-pin compatible with 8-lead SOIC versions of REF01/REF02/REF03, respectively, with the additional temperature monitoring function.

TERMINOLOGY

Temperature Coefficient

The change of output voltage with respect to operating temperature changes normalized by the output voltage at 25°C. This parameter is expressed in ppm/°C and can be determined by the following equation:

Line Regulation

The change in output voltage due to a specified change in input voltage. This parameter accounts for the effects of self-heating. Line regulation is expressed in either percent per volt, parts-per-million per volt, or microvolts per volt change in input voltage.

Load Regulation

The change in output voltage due to a specified change in load current. This parameter accounts for the effects of self-heating. Load regulation is expressed in either microvolts per milliampere, parts-per-million per milliampere, or ohms of dc output resistance.

The majority of the shift is seen in the first 200 hours, and as time goes by, the drift decreases significantly. This drift is much

smaller for the subsequent 1000 hours of time points than for the first.

Thermal Hysteresis

The change of output voltage after the device is cycled through temperatures from +25°C to –40°C to +125°C and back to +25°C. This is a typical value from a sample of parts put through such a cycle.

Input Capacitor

Input capacitors are not required on the ADR01/ADR02/ ADR03/ADR06. There is no limit to the value of the capacitor used on the input, but a 1 μF to 10 μF capacitor on the input improves transient response in applications where the supply suddenly changes. An additional 0.1 μF in parallel also helps to reduce noise from the supply.

Output Capacitor

The ADR01/ADR02/ADR03/ADR06 do not require output capacitors for stability under any load condition. An output capacitor, typically 0.1 μF, filters out any low-level noise voltage and does not affect the operation of the part. Alternatively, the load transient response can be improved with an additional 1 μF to 10 μF output capacitor in parallel. A capacitor here acts as a source of stored energy for a sudden increase in load current. The only parameter that degrades by adding an output capacitor is the turn-on time, and it depends on the size of the capacitor chosen.

APPLICATIONS

The ADR01/ADR02/ADR03/ADR06 are high precision, low drift 10.0 V, 5.0 V, 2.5 V, and 3.0 V voltage references available in an ultracompact footprint. The 8-lead SOIC versions of the devices are drop-in replacements of the REF01/REF02/REF03 sockets with improved cost and performance.

These devices are standard band gap references (see Figure 35). The band gap cell contains two NPN transistors (Q18 and Q19) that differ in emitter area by 2×. The difference in their V

BE

produces a proportional-to-absolute temperature current (PTAT) in R14, and, when combined with the V produces a band gap voltage, V

, that is almost constant in

BG

of Q19,

BE

temperature. With an internal op amp and the feedback network of R5 and R6, V

is set precisely at 10.0 V, 5.0 V, 2.5 V,

O

and 3.0 V for the ADR01, ADR02, ADR06, and ADR03, respectively. Precision laser trimming of the resistors and other proprietary circuit techniques are used to further enhance the initial accuracy, temperature curvature, and drift performance of the ADR01/ADR02/ADR03/ADR06.

The PTAT voltage is made available at the TEMP pin of the ADR01/ADR02/ADR03/ADR06. It has a stable 1.96 mV/°C temperature coefficient, such that users can estimate the temperature change of the device by knowing the voltage change at the TEMP pin.

APPLYING THE ADR01/ADR02/ADR03/ADR06

The devices can be used without any external components to achieve the specified performance. Because of the internal op amp amplifying the band gap cell to 10.0 V/5.0 V/2.5 V/3.0 V, power supply decoupling helps the transient response of the ADR01/ADR02/ADR03/ADR06. As a result, a 0.1 μF ceramic type decoupling capacitor should be applied as close as possible to the input and output pins of the device. An optional 1 μF to 10 μF bypass capacitor can also be applied at the V maintain the input under transient disturbance.

Output Adjustment

The ADR01/ADR02/ADR03/ADR06 trim terminal can be used to adjust the output voltage over a nominal voltage. This feature allows a system designer to trim system errors by setting the reference to a voltage other than 10.0 V/5.0 V/2.5 V/3.0 V. For finer adjustment, add a series resistor of 470 kΩ. With the configuration shown in Figure 36, the ADR01 can be adjusted from

9.70 V to 10.05 V, the ADR02 can be adjusted from 4.95 V to

5.02 V, the ADR06 can be adjusted from 2.8 V to 3.3 V, and the ADR03 can be adjusted from 2.3 V to 2.8 V. Adjustment of the output does not significantly affect the temperature performance of the device, provided the temperature coefficients of the resistors are relatively low.

Temperature Monitoring

As described at the end of the Applications section, the ADR01/ ADR02/ADR03/ADR06 provide a TEMP output (Pin 1 in Figure 1 and Pin 3 in Figure 2) that varies linearly with temperature. This output can be used to monitor the temperature change in the system. The voltage at V and the temperature coefficient is approximately 1.96 mV/°C (see Figure 37). A voltage change of 39.2 mV at the TEMP pin corresponds to a 20°C change in temperature.

Figure 37. Voltage at TEMP Pin vs. Temperature

The TEMP function is provided as a convenience rather than a precise feature. Because the voltage at the TEMP node is acquired from the band gap core, current pulling from this pin has a significant effect on V

. Care must be taken to buffer the

PROGRAMMABLE 4 mA TO 20 mA CURRENT TRANSMITTER

Because of their precision, adequate current handling, and small footprint, the devices are suitable as the reference sources for many high performance converter circuits. One of these applications is the multichannel 16-bit, 4 mA to 20 mA current transmitter in the industrial control market (see Figure 42). This circuit employs a Howland current pump at the output to yield better efficiency, a lower component count, and a higher voltage compliance than the conventional design with op amps and MOSFETs. In this circuit, if the resistors are matched such that R1 = R1

In this circuit, an ADR01 provides the stable 10.000 V reference for the AD5544 quad 16-bit DAC. The resolution of the adjustable current is 0.3 μA/step; the total worst-case INL error is merely 4 LSBs. Such error is equivalent to 1.2 μA or a 0.006% system error, which is well below most systems’ requirements. The result is shown in Figure 43 with measurement taken at 25°C and 70°C; total system error of 4 LSBs at both 25°C and 70°C.

where D is similarly the decimal equivalent of the DAC input code and N is the number of bits of the DAC.

According to Equation 2, R3′ can be used to set the sensitivity. R3′ can be made as small as necessary to achieve the current needed within U4 output current driving capability. Alternatively, other resistors can be kept high to conserve power.

In this circuit, the AD8512 is capable of delivering 20 mA of current, and the voltage compliance approaches 15.0 V.
