AFE4900YZR

Analog Front End (AFE) Overview

The AFE4900YZR is an ultra-low-power integrated analog front-end (AFE) manufactured by Texas Instruments. It features a 24-bit resolution with a sampling rate of 1 kS/s across three channels. The device supports I2C and SPI interfaces for digital communication. It operates within a supply voltage range of 1.7 V to 5.25 V and functions in temperatures from -20°C to +70°C. Packaged in a DSBGA-30 format, it is designed for biosensing applications requiring high precision and low power consumption.
