TLV320AIC23BGQE

Codecs Overview

The TLV320AIC23BGQE is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 32-pin MicroStar Junior package. It supports sampling rates from 8 kHz to 96 kHz with data word lengths of 16, 20, 24, and 32 bits. The device features a third-order multibit sigma-delta ADC with up to 90-dBA SNR and a second-order multibit DAC with up to 100-dBA SNR at 48 kHz. Operating conditions include a digital core supply (DVDD) of 1.42 V to 3.6 V and analog/buffer supplies (AVDD/BVDD) of 2.7 V to 3.6 V. The commercial temperature range is specified from -10°C to 70°C.

• MP3 digital audio players

Codecs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the package type and temperature rating. Confirm that the component meets all required electrical specifications for the intended operating environment before integration.

Codecs Selection Notes

Select this model when a compact form factor is required, as it utilizes the industry's smallest package option. Ensure the design accommodates the specific voltage requirements for DVDD and AVDD. Verify compatibility with the target digital audio interface protocol and clocking scheme.

Codecs Part Context

This component belongs to the TLV320AIC23B series of stereo audio codecs. The GQE suffix specifically denotes the 32-pin MicroStar Junior package variant designed for space-constrained portable applications. Other variants in the series include TSSOP and PQFP packages.

Codecs Replacement Considerations

Direct replacements within the same package and temperature range include the TLV320AIC23BIGQE. Cross-package substitutions require careful evaluation of pinout compatibility and thermal management requirements.
