MT8870 is a DTMF Decoder module that generates a 4-bit digital code with respect to the DTMF audio signal. The MT8870 Decoder IC is integrated with an operational amplifier with user-adjustable Guard time. The embedded band-split filter uses switch capacitor techniques to distinguish and split low and high frequencies from the received signal.
