TLV320AIC23BIZQE

Overview

The TLV320AIC23BIZQE is a high-performance stereo audio codec from Texas Instruments, housed in a 32-pin MicroStar Junior package. It supports sampling rates from 8 kHz to 96 kHz with word lengths of 16, 20, 24, and 32 bits. The device features a multibit sigma-delta ADC with up to 90-dBA SNR and a DAC with up to 100-dBA SNR at 48 kHz. Operating voltages include a digital core supply (DVDD) of 1.42 V to 3.6 V and analog/buffer supplies (AVDD, BVDD, HPVDD) of 2.7 V to 3.6 V. It operates within an industrial temperature range of -40°C to 85°C.

Feature Summary

• Integrates stereo-line inputs, microphone biasing, and a headphone amplifier with volume control.
• Supports software control via SPI or 2-wire compatible serial protocols for flexible DSP interfacing.
• Features low power consumption with programmable shutdown modes for extended battery life.
• Includes an internal oscillator optimized for direct connection to 12-MHz crystals.

Applications

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

Procurement Notes

Verify the specific suffix 'ZQE' against the manufacturer's current ordering information to confirm package type and temperature grade. Confirm that the component meets RoHS compliance requirements for your target market. Check for any end-of-life notices or obsolescence warnings directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a compact solution with integrated headphone amplification is required. Ensure the design accommodates the 32-pin MicroStar Junior footprint. Verify that the system clock requirements align with the internal oscillator capabilities and that the voltage domains match the DVDD and AVDD specifications.

Part Context

This part belongs to the TLV320AIC23B family of stereo audio codecs. The 'ZQE' suffix indicates the 32-pin MicroStar Junior package variant designed for space-constrained applications. Other variants in the series include TSSOP and PQFP packages, offering different board area trade-offs while maintaining identical electrical performance characteristics.

Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in the provided documentation. Consider evaluating other members of the TLV320AIC23B family with different package suffixes if form factor changes are acceptable. Cross-reference with TI's recommended upgrades for discontinued components.
