TLC320AC02CFNR

Codecs Overview

The Texas Instruments TLC320AC02CFNR is a single-supply analog interface circuit (AIC) designed for audio-band signal processing. It integrates a 14-bit resolution analog-to-digital converter (ADC) and a 14-bit digital-to-analog converter (DAC). The device features programmable switched-capacitor filters, including an antialiasing input filter and an output-reconstruction filter with (sin x)/x compensation. It operates on a single 5-V power supply with typical power dissipation of 100 mW. The component supports serial port interfaces for data and control transfers, accommodating master, slave, and stand-alone modes. It is characterized for commercial operation from 0°C to 70°C.

Codecs Procurement Notes

Verify the specific suffix CFNR against official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements and serial interface timing constraints before integration. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations.

Codecs Selection Notes

Select this component for applications requiring integrated analog front-end processing with minimal external filtering. Consider the available filter bandwidths and conversion rates when designing for specific audio frequencies. Evaluate the serial interface requirements to determine if master or slave mode suits the system architecture.

Codecs Part Context

The TLC320AC02 belongs to the Texas Instruments AIC family, functionally equivalent to the TLC320AC01 but with distinct electrical specifications. It serves as a monolithic CMOS solution for converting audio signals between analog and digital domains, simplifying system design by combining filtering, conversion, and interface logic on a single chip.

Codecs Replacement Considerations

The TLC320AC01 is functionally equivalent but differs in electrical specifications. Verify performance parameters against the specific application requirements when substituting.
