STLC5046 Datasheet - STMicroelectronics

DESCRIPTION
The STLC5046 is a monolithic programmable 4 channel codec and filter. It operates with a single +3.3V supply. The analog interface is based on a receive output buffer driving the SLIC RX input and on an amplifier input stage. Due to the single supply voltage a proper midsupply reference level is generated internally by the device and all analog signals are referred to this level (AGND). The PCM interface uses one common 8KHz frame sync. pulse for transmit and receive direction.
