AD570/AD570S is an analog-to-digital converter produced by Texas Instruments. Its features include 8-bit resolution, temperature range of 0-70°C, power supply range of +4.5-+5.5V, input range of 0-10V, and output coding of positive true binary or positive offset binary.
The AD570 is a complete 8-bit A/D converter designed for industrial and military applications. It requires no external components to perform successive-approximation analog-to-digital conversion and is specified for optimum performance using a +5 V and –15 V supply. The device features a temperature compensated buried Zener reference and a 5 kΩ thin-film input resistor.
The document details the circuit description, pin connections, and operating modes including unipolar (0 V to +10 V) and bipolar (–5 V to +5 V) ranges. It provides instructions for full-scale calibration, zero offset adjustment, and common-mode range management, along with timing diagrams for control and operation.

The device is designed for optimum performance using a +5 V and –15 V supply.
The device operates with a positive supply between +4.5 V and +5.5 V, and a negative supply between –16.0 V and –13.5 V.
The conversion cycle typically completes in 25 µs, though it can take up to 40 µs under specified conditions.
The absolute maximum power dissipation allowed for the AD570 is 800 mW.
