AFE1137E

Analog Front End (AFE) Overview

The AFE1137E is a Burr-Brown analog front-end integrated circuit designed for high-precision data acquisition applications. It integrates a 14-bit analog-to-digital converter with programmable gain amplifiers and signal conditioning circuits on a single chip. This integration reduces component count and board space while maintaining signal integrity. The device supports multiple input ranges and offers low noise performance suitable for industrial sensing, medical instrumentation, and test equipment requiring accurate analog signal digitization.
