TLV320AIC23BRHDR

Codecs Overview

The TLV320AIC23BRHDR 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 an analog supply voltage range of 2.7 V to 3.6 V and a digital core supply of 1.42 V to 3.6 V. It provides a signal-to-noise ratio of up to 90 dB for the ADC and 100 dB for the DAC at 48 kHz sampling. The component includes integrated headphone amplifiers capable of delivering 30 mW per channel into 32 Ω loads.

• Glueless interface compatibility with TI McBSP digital signal processors

Codecs Applications

• Portable solid-state audio players and recorders
• Digital voice encryption systems
• High-fidelity recording equipment

Codecs Procurement Notes

Verify component authenticity through official Texas Instruments channels or authorized distributors. Confirm that the specific ordering suffix matches the required commercial temperature range (-10°C to 70°C). Ensure the package type corresponds to the design footprint requirements. Check for current lifecycle status as older revisions may be discontinued.

Codecs Selection Notes

Select this model when a PQFP package is preferred over TSSOP or MicroStar Junior formats. Ensure the system design supports the required dual-supply voltage architecture for analog and digital sections. Verify that the host processor can interface via the supported SPI or 2-wire control protocols. Consider the physical board space constraints associated with the 28-pin PQFP outline.

Codecs Part Context

This component belongs to the TLV320AIC23B family of stereo audio codecs. It shares functional specifications with other variants such as the BPWG4 and BIRHDG4, differing primarily in package style and temperature rating. The RHD suffix specifically denotes the 28-pin plastic quad flat pack configuration suitable for surface-mount assembly.

Codecs Replacement Considerations

Public confirmed substitute part numbers include TLV320AIC23BIPW and TLV320AIC23BIGQE. These alternatives offer identical electrical performance but utilize different package types such as TSSOP or MicroStar Junior.
