Description

The MCP2035 is an Analog Front-End (AFE) optimized for BodyCom applications. It is a single-channel stand-alone device for low-frequency (LF) signal detection and low-power short range transponder applications, such as BodyCom communications. The device can detect an input signal with amplitude as low as ~1 mVPP, and can demodulate an amplitude-modulated input signal with as low as 8% modulation depth.
