ADS8638SRGER TI ADC | 24-VQFN (4x4) | 8-Ch, 500kSPS, 12-Bit, SPI

Product Overview

The ADS8638SRGER is a high-performance, 12-bit, 8-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates from a single 2.7V to 5.25V supply and features a maximum sampling rate of 500 kSPS. The device includes an internal reference, a reference buffer, and a programmable sequencer, making it ideal for multi-channel data acquisition systems. The compact 24-VQFN (4x4) package enables space-constrained designs.
