TLC320AC01CFNR

Codecs Overview

The TLC320AC01CFNR is a single-channel audio codec manufactured by Texas Instruments, designed for high-fidelity analog-to-digital and digital-to-analog conversion. It features a 14-bit resolution with a maximum sampling rate of 25 kHz, supporting both mono input and output configurations. The device operates on a single 5V supply voltage ranging from 4.5 V to 5.5 V. It utilizes a serial interface compatible with standard DSP protocols. Housed in a 28-pin PLCC package, it functions within an industrial temperature range of -40°C to +85°C.

Codecs Feature Summary

• Integrates a single microphone preamplifier, ADC, DAC, and headphone amplifier into one component
• Supports direct connection to microphones without requiring external preamplification stages
• Includes programmable gain control for the microphone input stage

Codecs Applications

• Voice recognition systems
• Telecommunication handsets
• Dictation devices

Codecs Procurement Notes

Verify the specific suffix 'CFNR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging and lead-free status. Ensure the ordering information matches the exact pinout and thermal characteristics required for the target PCB layout before finalizing procurement orders.

Codecs Selection Notes

Select this component when a single-channel audio path with integrated microphone amplification is required. It is suitable for applications where power consumption must be minimized while maintaining acceptable audio quality for voice frequencies. Compare performance metrics against higher-resolution alternatives if music-grade fidelity is necessary.

Codecs Part Context

This part belongs to the TLC320ACxx family of audio codecs, which are widely used in portable electronic devices. The AC01 variant specifically targets mono audio applications, distinguishing itself from stereo counterparts like the AC02. It serves as a cost-effective solution for basic voice processing tasks in embedded systems.

Codecs Replacement Considerations

Direct replacements include the TLC320AC02IFNR for stereo applications or other members of the TLC320ACxx series. Verify pin compatibility and software register settings when substituting with similar codecs from Texas Instruments or other manufacturers.
