TLV320AIC23BZQER

Codecs Overview

The TLV320AIC23BZQER is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 32-pin MicroStar Junior package. It integrates sigma-delta ADCs and DACs supporting sample rates from 8 kHz to 96 kHz with word lengths of 16, 20, 24, or 32 bits. The device features an SNR of up to 90 dB for the ADC and 100 dB for the DAC at 48 kHz sampling. Power supplies include DVDD (1.42 V to 3.6 V), BVDD (2.7 V to 3.6 V), and AVDD/HPVDD (2.7 V to 3.6 V). It operates within an industrial temperature range of -40°C to 85°C.

Codecs Feature Summary

• Integrates multibit sigma-delta modulators for high-fidelity analog-to-digital and digital-to-analog conversion.
• Includes a highly efficient linear headphone amplifier capable of delivering power into low-impedance loads.
• Provides complete electret microphone biasing and buffering solutions with adjustable gain control.
• Supports flexible software-controlled power management for extended battery life in portable devices.

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 ordering suffix matches the required package type and temperature rating. Ensure the latest datasheet revision is referenced during design-in to account for any potential updates to electrical characteristics or pin configurations.

Codecs Selection Notes

Select this component when a compact form factor is critical due to its industry-leading small package size. Evaluate power consumption requirements against the specified playback and standby modes. Ensure the host system supports the required serial interface protocols for configuration and data transfer.

Codecs Part Context

This part belongs to the TLV320AIC23B family of stereo audio codecs. It shares core functional specifications with other variants in the series but differs in physical packaging and thermal operating ranges. The ZQE suffix specifically denotes the 32-pin MicroStar Junior package suitable for space-constrained designs.

Codecs Replacement Considerations

Direct replacements include TLV320AIC23BIGQE for the same package and temperature range. Other package variants such as TLV320AIC23BPW (TSSOP) offer equivalent functionality with different footprint requirements.
