MT8870 DTMF RECEIVER

MT8870 DTMF Decoder 

The MT8870D/MT8870D-1 is a complete DTMF receiver integrating both the band split 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. External component count is minimized by on chip provision of a differential input amplifier, clock oscillator and latched three-state bus interface.

  • Complete DTMF Receiver
  • Low power consumption
  • Internal gain setting amplifier
  • Adjustable guard time
  • Central office quality
  • Power-down mode
  • Inhibit mode
  • Backward compatible with MT8870C/MT8870C-1

Applications of MT8870
