The AD7170 is a low power 12-bit analog-to-digital converter (ADC) with an output data rate of 125 Hz, pin-programmable power-down and reset, status function, internal clock oscillator, current of 135 μA, power supply range of 2.7 V to 5.25 V, temperature range of -40°C to +105°C, etc.
The AD7170 is a very low‑power 12‑bit sigma‑delta analog‑to‑digital converter that includes an on‑chip oscillator and a pin‑programmable power‑down mode. It operates from a 2.7 V to 5.25 V supply, consumes 135 µA in normal mode and only 5 µA in power‑down, and provides a 125 Hz output data rate with 12‑bit resolution.
Typical applications include pressure measurement, industrial process control, and portable instrumentation. The device is offered in a 10‑lead 3 mm × 3 mm LFCSP package and features a single differential input, SPI‑compatible serial interface, and a range of protection and performance specifications suitable for battery‑operated systems.
