The DTMF Decoder Click Board? is a compact add-on board that contains an integrated DTMF receiver with enhanced sensitivity. This board features the MT8870D, a complete DTMF receiver integrating the band-split filter and digital decoder functions from Microchip Technology. It offers low power consumption and high performance and uses digital counting techniques to detect and decode all 16 DTMF tone-pairs into a 4-bit code. Whenever a valid tone is detected, it outputs the associated value in binary on four LEDs, with an additional indicator that strobes after each new tone. This Click Board? is suitable for paging systems, remote control, electronic communications circuits, and various other applications.
