ADS8867IDGS

Analog To Digital Converters (ADC) Overview

The ADS8867IDGS is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 100 kSPS and features true differential inputs. The device requires an analog supply voltage ranging from 2.7 V to 3.6 V and a digital supply voltage between 1.65 V and 3.6 V. Key performance metrics include a signal-to-noise ratio (SNR) of 96 dB and a signal-to-noise and distortion ratio (SINAD) of 96.4 dB. It utilizes an external reference voltage of 5 V and communicates via an SPI interface. The component is housed in a 10-lead MSOP package and supports daisy-chaining capabilities.
