MT8870DS MT8870D SOIC-18 ISO2-CMOS Integrated DTMF Receiver IC

Description

Description: The MT8870D/MT8870D-1 is a complete 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 tone-pairs into a 4-bit code.
