Overview
The TLC320AC02IPM, manufactured by Texas Instruments, is a single-supply analog interface circuit (AIC) designed for audio-band processing. This device integrates a comprehensive set of features including 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, and a serial port for data and control transfers. The TLC320AC02IPM operates in three basic modes: stand-alone analog-interface mode, master-slave mode, and linear-codec mode, making it versatile for various applications.
