KA8501A SPEECH NETWORK WITH DIALER INTERFACE
INTRODUCTION
The KA8501A is a telephone speech network in-
tegrated circuit which includes transmit amp, receive
amp, DTMF amp, voltage regulator, line equalizer,
voltage comparator. It handles the voice signal, perfor-
ming the 2/4 wires interface and changing the gain on
both sending and receiving amplifiers to compensate
the line current. The KA8501A can work in fixed gain
mode.
FEATURES
Adjusts sending and receiving attenuation length
Regulated voltage for dialer
Linear interface for DTMF
Suitable for ceramic transducers
Mute function
