KA2425A

SPEECH NETWORK WITH DIALER INTERFACE

INTRODUCTION

The KA2425A is telephone speech network integrated

circuit which includes transmit amp, receive amp,

side tone amp, DC loop interface function, DTMF input,

voltage regulator for speech, a regulated output voltage

for a dialer, and equalization circuit .

FEATURES

• Low voltage operation (1.5v : speech)

• Transmit, receive, side tone and DTMF level are

controlled by external resistors

• Regulated voltage for dialer

• Loop length equalization

• MUTE function

• Linear interface for DTMF
