The AD570SD is an 8-bit successive approximation (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices. It offers a single ended analog input, parallel data output, and an internal reference voltage. The converter provides two analog input range options: unipolar 0V to +10V and bipolar -5V to +5V. Typical conversion time is 25 µs, with a minimum of 15 µs and a maximum of 40 µs.
The device operates from a dual power supply: V+ from +4.5V to +7.0V and V- from -12.0V to -16.5V. Typical supply currents are 7 mA on V+ and 9 mA minimum to 15 mA maximum on V-. Accuracy specifications include ±½ LSB relative accuracy, ±2 LSB full-scale calibration error, and ±½ LSB unipolar and bipolar offset errors. Output coding is positive true binary for unipolar mode and positive true offset binary for bipolar mode.
The AD570SD is designed for the military temperature range -55°C to +125°C. It is housed in an 18-pin ceramic dual in-line package (18-CDIP, 0.300" width, 7.62mm) with through hole mounting. Logic inputs are TTL compatible with VIH minimum 2.0V and VIL maximum 0.8V. The logic output can sink 3.2 mA minimum and source 0.5 mA minimum.
This ADC is suitable for industrial and military applications requiring reliable performance over a wide temperature range. The datasheet text extract covers both AD570J (commercial) and AD570S (military) grades, with the AD570SD being the specific military grade part.
V+ supply voltage range: +4.5V to +7.0V. V- supply voltage range: -12.0V to -16.5V.
