Product Summary
The S1T8503X01-D0 is a low voltage speech network which includes Mic amp. transmit amp, side-tone amp, and 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. Each gain can be controlled by external component exchange. The receiver output driving capability is adjustable.
