The TLC320AC01 analog interface circuit (AIC) is an audio-band processor that provides an analog-to-digital and digital-to-analog input/output interface system on a single monolithic CMOS chip. This device integrates a band-pass switched-capacitor antialiasing input filter, a 14-bit-resolution analog-to-digital converter (ADC), a 14-bit-resolution digital-to-analog converter (DAC), a low-pass switched-capacitor output-reconstruction filter, (sin x)/x compensation, and a serial port for data and control transfers.
The major functions of the TLC320AC01 are:
- To convert audio-signal data to digital format by the ADC channel
- To provide the interface and control logic to transfer data between its serial input and output terminals and a digital signal processor (DSP) or microprocessor
- To convert received digital data back to an audio signal through the DAC channel
