Description

The KK3726AN is a low voltage speech network which includes Mic amp. transmit amp, receive amp. and stabilized DC-supply 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.
