Product Overview

The MT8870 is an efficient DTMF receiver incorporating both the bandsplit filter and digital decoder functions. The filter segment uses switched capacitor techniques for low and high set filters; the decoder utilizes digital counting techniques to detect and decode all 16 DTMF tone-pairs to a 4-bit code. External component count is lessened by on chip supply of a differential input amplifier, clock oscillator and latched three-state bus port.
