S1T8501 is SPEECH NETWORK WITH DIALER INTERFACE manufactured by Samsung Semiconductor.
SPEECH NETWORK WITH DIALER INTERFACE
INTRODUCTION
The S1T8501 is a speech network integrated circuit which includes the following ponents: transmit amp, receive amp, DTMF amp, voltage regulator, line equalizer, and voltage parator. It handles the voice signal, performing the 2/4 wires interface and changing the gain on both sending and receiving amplifiers to pensate the line current. The S1T8501 can work in fixed gain mode.
