Applications

•

Credit card systems

Paging systems

The receiver section is based upon the industry

standard MT8870 DTMF receiver while the transmitter

utilizes a switched capacitor D/A converter for low

distortion, high accuracy DTMF signalling. Internal

counters provide a burst mode such that tone bursts

can be transmitted with precise timing. A call progress

filter can be selected allowing a microprocessor to

analyze call progress tones.

Description

The MT8889C utilizes an adaptive micro interface,

which allows the device to be connected to a number

of popular microcontrollers with minimal external logic.

The MT8889C is a monolithic DTMF transceiver with

call progress filter. It is fabricated in CMOS technology

offering low power consumption and high reliability.
