TLV320AIC23BPWRG4

Codecs Overview

The TLV320AIC23BPWRG4 is a low-power stereo audio codec manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It features a 1.42 V to 3.6 V digital core supply and a 2.7 V to 3.6 V analog/buffer supply. The device supports sampling rates from 8 kHz to 96 kHz with data word lengths of 16, 20, 24, or 32 bits. It integrates a third-order multibit sigma-delta ADC with up to 90 dB SNR and a second-order multibit sigma-delta DAC with up to 100 dB SNR at 48 kHz. The codec includes a stereo headphone amplifier capable of delivering 30 mW into 32 Ω, electret microphone biasing, and an analog bypass path.

Codecs Feature Summary

• Integrates highly efficient linear headphone amplifiers with volume control and mute capabilities.
• Provides complete electret microphone biasing and buffering solutions with programmable gain.
• Supports flexible power management allowing selective shutdown of functions for extended battery life.
• Features software control via TI McBSP-compatible multiprotocol serial ports including SPI and 2-wire interfaces.

Codecs Applications

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

Codecs Procurement Notes

Verify the component status as discontinued through official Texas Instruments channels before design finalization. Confirm that the specific ordering suffix corresponds to the required industrial temperature range and packaging format. Ensure compatibility with existing system voltage levels and interface protocols during the transition phase.

Codecs Selection Notes

Select this component when designing portable audio systems requiring high-fidelity stereo conversion within a compact footprint. Verify that the available 28-pin TSSOP package meets the board space constraints compared to smaller alternatives like MicroStar Junior. Ensure the host processor supports the required McBSP-compatible serial interface protocols for configuration and data transfer.

Codecs Part Context

This part belongs to the TLV320AIC23B series of low-power stereo codecs. It shares functional similarities with other members of the family but differs in package type and specific thermal ratings. The 'PW' suffix indicates the 28-pin Thin Shrink Small Outline Package (TSSOP), while 'G4' denotes lead-free and RoHS-compliant manufacturing standards.

Codecs Replacement Considerations

Direct replacements include the TLV320AIC23BIPW and TLV320AIC23BRHD. These variants offer identical electrical performance but differ in operating temperature ranges and physical package styles. Verify pinout compatibility and thermal characteristics when substituting.
