TLV320AIC23BPWR

Codecs Overview

The TLV320AIC23BPWR is a low-power stereo audio codec manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It features a multibit sigma-delta ADC with up to 90-dBA SNR and a DAC with up to 100-dBA SNR at 48 kHz sampling rates. The device supports data word lengths of 16, 20, 24, and 32 bits with sample rates ranging from 8 kHz to 96 kHz. Power supplies include a digital core voltage (DVDD) of 1.42 V to 3.6 V and analog/buffer voltages (AVDD, BVDD, HPVDD) of 2.7 V to 3.6 V. It integrates a stereo headphone amplifier capable of delivering 30 mW into 32 Ω loads.

Codecs Feature Summary

• Integrates highly efficient linear headphone amplifiers with analog volume control and mute functions.
• Supports software-controlled power management for selective shutdown of codec functions to extend battery life.
• Includes complete electret microphone biasing and buffering solutions with tunable gain capabilities.

Codecs Applications

• Portable solid-state audio players
• Digital audio recorders
• MP3 digital audio players

Codecs Procurement Notes

Verify the component status before procurement as this specific part number may be discontinued or subject to change. Confirm that the 28-pin TSSOP package aligns with your PCB footprint requirements. Ensure that the industrial temperature range specifications meet your operational environment needs. Cross-reference the ordering information to confirm availability of equivalent packages if necessary.

Codecs Selection Notes

Select this component when designing portable audio systems requiring high-fidelity stereo conversion with minimal power consumption. The integrated headphone amplifier eliminates the need for external drivers. Ensure compatibility with the host processor's McBSP interface for glueless connection. Verify that the required oversampling rates match the system clock constraints.

Codecs Part Context

This component belongs to the TLV320AIC23B family of stereo audio codecs. It is designed to provide a compact, cost-effective analog I/O solution for portable devices. The BPWR suffix indicates the 28-pin TSSOP package variant within this series, offering a smaller board area compared to larger packages while maintaining full functional integration.

Codecs Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as other package variants like the MicroStar Junior or PQFP versions. Verify if newer generations of audio codecs offer improved performance metrics while maintaining interface compatibility.
