TLV320AIC23BRHD

Codecs Overview

The TLV320AIC23BRHD is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 28-pin RHD (PQFP) package. It features multibit sigma-delta ADC and DAC architectures supporting sample rates from 8 kHz to 96 kHz with word lengths of 16, 20, 24, or 32 bits. The device operates with a digital core supply (DVDD) ranging from 1.42 V to 3.6 V and analog/buffer supplies (AVDD/BVDD) from 2.7 V to 3.6 V. It delivers an ADC signal-to-noise ratio of up to 90 dBA and a DAC SNR of up to 100 dBA at 48 kHz sampling. Playback power consumption is approximately 23 mW.

Codecs Feature Summary

• Integrates highly efficient linear headphone amplifiers capable of delivering 30 mW per channel into 32-ohm loads.
• Includes complete electret microphone biasing and buffering solutions with tunable fixed gain and programmable boost capabilities.
• Supports flexible software-controlled power management for selective shutdown of internal functions to extend battery life.
• Features an analog bypass path allowing direct routing of stereo-line inputs to outputs while utilizing the headphone amplifier.

Codecs Applications

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

Codecs Procurement Notes

Verify component authenticity through authorized distributors or TI directly. Confirm the specific ordering suffix matches the required industrial temperature range (-40°C to 85°C). Ensure compatibility with existing PCB footprints for the 28-pin PQFP package before finalizing procurement decisions.

Codecs Selection Notes

Select this model when a glueless interface to TI McBSP-compatible processors is required. Choose the RHD package variant specifically for applications necessitating a 28-pin plastic quad flat pack footprint. Verify that the system design accommodates the distinct DVDD and AVDD/BVDD power supply requirements outlined in the recommended operating conditions.

Codecs Part Context

This component belongs to the TLV320AIC23B series of low-power stereo codecs. It shares functional similarities with other variants in the family but differs in packaging options such as MicroStar Junior or TSSOP. The BRHD designation specifically identifies the 28-pin PQFP package configuration within the broader product line.

Codecs Replacement Considerations

Direct pin-compatible replacements include other packages within the same family, such as TLV320AIC23BPW (TSSOP) or TLV320AIC23BIGQE (MicroStar Junior), provided the board layout supports the alternative form factors.
