AMC7812SPAPR TI Analog Front End | 64-HTQFP (10x10) | 12-Bit, 8-Ch, SPI

Product Overview

The AMC7812SPAPR from Texas Instruments is a complete analog front-end (AFE) device designed for precision data acquisition systems. It integrates a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) with an 8-channel input multiplexer, a programmable gain amplifier (PGA), and a precision voltage reference. The device operates from a single 2.7V to 5.5V supply and communicates via a 4-wire SPI interface. Housed in a compact 64-pin HTQFP (10x10 mm) package, it is ideal for space-constrained applications requiring high accuracy and low power consumption.
