CMOS Integrated DTMF Receiver

The CAMD CM8870 CM8870C provides full DTMF receiver capability by integrating both the band-split Filter and digital decoder functions into a single 18-pin DIP, SOIC, or 20-pin PLCC package. The CM8870 70C is manufac- tured using state-of-the-art CMOS process technology for low power consumption (35mW, MAX) and precise data handling. The Filter section uses a switched capaci- tor technique for both high and low group Filters and dial By California Micro Devices Corporation
