KA8503 LOW VOLTAGE SPEECH NETWORK
INTRODUCTION
The KA8503 is a telephone low voltage speech network which includes
mic amp. transmit amp, side-tone amp, receive amp. It handles the
voice signal performing the 2/4 wire interface and changing the gain
on both sending and receiving amplifiers to compensate for line at-
tenuation by sensing the line length through the line current. Applica-
tion dependent parameters such as amplitude of each amp, sidetone
level line balance, and frequency response are controlled by exter-
nal components. Each gain can be controlled by external component
exchange. The receiver output driving capability is adjustable.
