TLV320AIC23BPWG4

Overview

The TLV320AIC23BPWG4 is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It integrates sigma-delta ADCs and DACs supporting data word lengths of 16, 20, 24, and 32 bits with sampling rates from 8 kHz to 96 kHz. The device operates with a digital core supply (DVDD) ranging from 1.42 V to 3.6 V and analog/buffer supplies (AVDD/BVDD) from 2.7 V to 3.6 V. It features an SNR of up to 90 dB for the ADC and 100 dB for the DAC at 48 kHz. Playback power consumption is less than 23 mW, while standby and power-down modes consume less than 150 µW and 15 µW respectively.

Feature Summary

• Integrates multibit sigma-delta modulation technology for high-fidelity audio conversion.
• Includes a highly efficient linear headphone amplifier capable of driving low-impedance loads.
• Supports flexible software control via SPI or 2-wire compatible serial protocols.
• Provides integrated electret microphone biasing and buffering solutions.

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'G4' indicates lead-free packaging compliance. Check current lifecycle status as this model may be discontinued or subject to replacement by newer series components.

Selection Notes

Select this component when designing portable audio systems requiring low power consumption and high dynamic range. Ensure the host processor supports the required I2S or McBSP interface timing. Verify that the system voltage rails align with the specified DVDD and AVDD operating ranges for optimal performance.

Part Context

This part belongs to the TLV320AIC23B family of stereo codecs. It shares functional specifications with variants such as the TLV320AIC23BIPW and TLV320AIC23BIGQE, differing primarily in package type and industrial temperature rating capabilities.

Replacement Considerations

Consult official documentation for direct substitutes like the TLV320AIC23BIPW. Evaluate pin compatibility and register map consistency before transitioning to alternative packages within the same product family.
