The MCP2030 is a stand-alone, Analog Front-End (AFE) device for Low-Frequency (LF) sensing and bidirectional communication applications. The device can output demodulated data, carrier clock or RSSI current. The demodulated data and carrier clock outputs are available on the LFDATA pin, while the RSSI output
is available on the RSSI pin. The RSSI current output is linearly proportional to the input signal strength. Device features are controlled by the programming of its internal Configuration registers.


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 an 8% modulation depth.
