Analog Devices AD570 8-Bit A/D Converter Datasheet
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.
