TLV320AIC23BIPWRG4

Codecs Overview

The TLV320AIC23BIPWRG4 is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It features multibit 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 provides an SNR of up to 90 dB for the ADC and 100 dB for the DAC at 48 kHz. The codec includes integrated headphone amplifiers capable of delivering 30 mW per channel into 32 Ω, stereo line inputs/outputs, and microphone biasing.

• Flexible power management with standby and power-down modes
• Software-controlled via SPI or 2-wire compatible serial protocols

Codecs Applications

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

Codecs Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'PW' corresponds to the 28-pin TSSOP package and 'G4' indicates lead-free compliance. Ensure the industrial temperature range (-40°C to 85°C) matches the application environment requirements before finalizing procurement.

Codecs Selection Notes

Select this model when a compact stereo codec with integrated headphone drivers is required. The industrial temperature rating makes it suitable for broader environmental conditions compared to commercial variants. Verify that the system design supports the necessary DVDD and AVDD voltage levels and utilizes a compatible serial interface protocol for register configuration.

Codecs Part Context

This component belongs to the TLV320AIC23B series, which offers various package options including MicroStar Junior and PQFP. The IPWRG4 designation specifically identifies the industrial grade version in the TSSOP-28 footprint. It serves as a complete analog I/O solution designed to minimize board space while providing high-quality audio processing capabilities for portable electronics.

Codecs Replacement Considerations

Direct replacements include other members of the TLV320AIC23B family such as TLV320AIC23BIGQE/ZQE (MicroStar Junior) or TLV320AIC23BIRHD (PQFP), provided the package dimensions are accommodated. Cross-package substitution requires careful review of pinout compatibility and thermal characteristics.
