The ADI Chinese version data manual is a translation of the English version data manual, which introduces the features and characteristics of AD7170 12-bit low power Σ-Δ ADC, including output data rate, pin functions, power requirements, temperature range, package type, interface type, etc.
The AD7170 is a 12-bit low power sigma-delta analog-to-digital converter (ADC) with an internal oscillator. It is designed for applications requiring very low power consumption, such as portable or battery-powered products. The device features a power-down mode with a current consumption of only 5 µA to extend battery life.
The AD7170 operates with a supply voltage ranging from 2.7 V to 5.25 V and is available in a 10-lead LFCSP package. It includes a differential input with a gain of 1 and provides an output data rate of 125 Hz. All features are controlled by dedicated pins, and each data read operation appends 8 status bits to the 12-bit conversion result. This manual is written in Chinese.
