Audio Codec 1ADC / 1DAC 15-Bit 32-Pin TQFP

The voice-band audio processor (VBAP) is designed to perform transmit encoding analog/digital (A/D) conversion, receive decoding digital/analog (D/A) conversion, and transmit and receive filtering for voice-band communications systems. The device operates in either the 15-bit linear or 8-bit companded (µ-law or A-Law) mode, which is selectable through the I2C interface. The VBAP generates its own internal clocks from a 2.048-MHz master clock input.
