The MT8870D/MT8870D-1 is a plete DTMF receiver integrating both the bandsplit filter and digital decoder functions.

The filter section uses switched capacitor techniques for high and low group filters;

the decoder uses digital counting techniques to detect and decode all 16 DTMF tonepairs into a 4-bit code.
