상세설명 :

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 attenuation by sensing the line length through the line current. Application  dependent parameters such as amplitude of each amp, sidetone level line balance, and frequency response are controlled by external components. Each gain can be controlled by external component exchange. The receiver output driving capability is adjustable.
