TLC320AC02CFN

Codecs Overview

The Texas Instruments TLC320AC02CFN 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 antialiasing and reconstruction filters with selectable bandwidths up to 10.8 kHz. 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 temperature operation from 0°C to 70°C.

Codecs Feature Summary

• Integrates 14-bit ADC and DAC channels with differential architecture throughout the signal path.
• Includes programmable switched-capacitor antialiasing input and output-reconstruction filters.
• Supports multiple operating modes including stand-alone, master-slave, and linear-codec configurations.
• Features monitor outputs and programmable gains for input, output, and monitoring amplifiers.

Codecs Applications

• Modems
• Speech processing systems
• Analog interfaces for digital signal processors (DSPs)
• Industrial process control instrumentation

Codecs Procurement Notes

Verify the specific suffix 'CFN' against the manufacturer's current datasheet SLAS084C to confirm package type and availability status. Ensure the commercial temperature range (0°C to 70°C) aligns with system requirements. Cross-reference pin assignments for the FN package to validate board layout compatibility before finalizing procurement orders.

Codecs Selection Notes

Select this component when a monolithic solution for 14-bit audio conversion with integrated filtering is required. Consider the fixed 5-V supply constraint and the specific filter bandwidth options available via register programming. Evaluate the serial interface timing requirements against the host processor capabilities in master or slave configurations.

Codecs Part Context

The TLC320AC02CFN belongs to the TLC320AC02 family of analog interface circuits. It is functionally equivalent to the TLC320AC01 but differs in electrical specifications. The 'C' suffix denotes the commercial temperature grade, while 'FN' indicates the PLCC-28 package variant. This part serves as a complete analog front-end for digital audio applications.

Codecs Replacement Considerations

The TLC320AC01 is functionally equivalent but has different electrical specifications. Verify if the alternative meets the specific gain and distortion requirements. No other direct substitutes are confirmed in the provided documentation.
