AFE4490RHAT TI Analog Front-End | 40-VQFN (6x6) | 4-Ch, 24-Bit ADC

Product Overview

The AFE4490RHAT is a highly integrated analog front-end (AFE) from Texas Instruments, designed for multi-channel data acquisition systems. It features four low-noise, 24-bit delta-sigma ADCs with programmable gain amplifiers (PGAs) and a built-in temperature sensor. The device operates from a single 2.7V to 5.5V supply and is housed in a compact 40-pin VQFN (6x6 mm) package. Its low power consumption and high precision make it ideal for portable and industrial applications.
