ADS8326IDRBR

Analog To Digital Converters (ADC) Overview

The ADS8326IDRBR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single pseudo-differential or single-ended input channel and operates on a sampling rate of 250 kS/s. The device supports both analog and digital power supplies ranging from 2.7 V to 5.5 V, consuming only 10 mW of power. It utilizes an external reference and communicates via an SPI-compatible interface. Key performance metrics include a signal-to-noise ratio of 91 dB, differential nonlinearity of -1/2 LSB, and integral nonlinearity of +/- 3 LSB. It functions within a temperature range of -40°C to +85°C in an 8-pin SON package.
