TLV320AIC23GQER

Codecs Overview

The TLV320AIC23GQER is a high-performance stereo audio codec from Texas Instruments, housed in a 32-pin MicroStar Junior package. It features multibit 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 integrates a headphone amplifier delivering 30 mW into 32 Ω, stereo line inputs, and microphone biasing. Digital interfaces include SPI and 2-wire control protocols alongside I2S-compatible audio data transfer. Operating voltages range from 1.42 V to 3.6 V for the digital core and 2.7 V to 3.6 V for analog supplies.

Codecs Feature Summary

• Integrates multibit sigma-delta converters with oversampling digital filters for high-fidelity audio processing.
• Includes an integrated electret microphone biasing solution with a tunable buffer amplifier.
• Features a highly efficient linear headphone amplifier with programmable volume control and mute capabilities.
• Supports flexible power management with software-controlled shutdown modes to extend battery life.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific ordering suffix GQER against the manufacturer's current datasheet to confirm the package type and temperature range. Ensure compatibility with system voltage requirements before integration. Check for any recent product discontinuation notices or lifecycle changes directly from the manufacturer.

Codecs Selection Notes

Select this component when a compact stereo codec with integrated headphone amplification is required. Verify that the available supply voltages match the system design constraints. Consider the package size limitations if board space is restricted, as this model utilizes a proprietary small footprint.

Codecs Part Context

This part belongs to the TLV320AIC23 family of stereo audio codecs. The GQER suffix indicates the 32-pin MicroStar Junior package variant. Other variants in the series include different package options such as TSSOP, catering to various board layout requirements while maintaining identical functional specifications.

Codecs Replacement Considerations

Direct replacements within the same family include the TLV320AIC23IPW or TLV320AIC23PW for alternative packaging. Cross-family upgrades may require interface and pinout verification.
