TLV320AIC23BZQE

Codecs Overview

The TLV320AIC23BZQE is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 32-pin MicroStar Junior 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 on a core digital supply (DVDD) ranging from 1.42 V to 3.6 V and analog/buffer supplies (AVDD, BVDD, HPVDD) from 2.7 V to 3.6 V. It includes an integrated headphone amplifier delivering 30 mW into 32 Ω, stereo-line inputs with programmable gain, and electret microphone biasing. Control interfaces include SPI and 2-wire protocols.

• Integrated stereo headphone amplifier with volume control and mute
• Flexible power management with software-selectable shutdown modes
• Supports industry-standard and optimized oversampling rates for DSP and USB compatibility

Codecs Applications

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

Codecs Procurement Notes

Verify the specific ordering suffix ZQE corresponds to the 32-pin MicroStar Junior package and commercial temperature range (-10°C to 70°C). Confirm that the component matches the SLWS106H datasheet revision. Ensure design safeguards are implemented as TI assumes no liability for application assistance or customer product design.

Codecs Selection Notes

Select this component when a compact analog I/O solution is required for portable audio designs. The MicroStar Junior package minimizes board area to 25 mm². Verify compatibility with the host processor's McBSP interface if using TI C54x DSPs. Ensure supply voltages align with the specified DVDD and AVDD ranges for optimal SNR performance.

Codecs Part Context

The TLV320AIC23BZQE belongs to the TLV320AIC23B family of stereo audio codecs. This series is designed for low-power, high-performance audio applications. Other packages in the family include the 28-pin TSSOP (PW) and 28-pin PQFP (RHD), offering flexibility in form factor while maintaining identical electrical characteristics and functionality.

Codecs Replacement Considerations

Direct pin-compatible replacements within the same package are not explicitly listed in the provided documentation. Consider the TLV320AIC23BPW (TSSOP) or TLV320AIC23BRHD (PQFP) if package adaptation is feasible. Verify functional equivalence regarding control interfaces and analog specifications before substitution.
