TLC320AC02IFN

Product Summary

The TLC320AC02IFN is a Single-Supply Analog Interface Circuit (AIC). The TLC320AC02IFN 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. The TLC320AC02IFN 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 internal circuit configuration and performance parameters are determined by reading control information into the eight available data registers. The register data sets up the device for a given mode of operation and application.
