This datasheet details the Analog Devices AD4111, a low-power, low-noise 24-bit sigma-delta ADC with integrated AFE for voltage and current inputs.
The AD4111 is a low-power, low-noise, 24-bit Sigma-Delta analog-to-digital converter (ADC) that integrates an analog front end (AFE). It supports fully differential or single-ended, high-impedance bipolar ±10 V voltage inputs and 0 mA to 20 mA current inputs. The device features a maximum channel scan rate of up to 6.2 kSPS per channel. This manual is written in Chinese.
