AMC7891SRHHT TI Analog Front-End | 36-VQFN (6x6) | 16-Bit, 8-Ch, 500kSPS

Product Overview

The AMC7891SRHHT is a high-performance, 16-bit, 8-channel simultaneous-sampling analog front-end (AFE) from Texas Instruments. It integrates a programmable gain amplifier (PGA), an internal reference, and a high-speed serial interface, making it ideal for multi-channel data acquisition systems. The device operates from a single 5V supply and features a 500kSPS per channel sampling rate. Housed in a compact 36-VQFN (6x6) package, it is designed for space-constrained applications requiring high accuracy and low power consumption.
