TLV320AIC31IRHBT

Codecs Overview

The TLV320AIC31IRHBT is a low-power stereo audio CODEC manufactured by Texas Instruments, designed for portable audio and telephony applications. It features two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs) with a resolution of 24 bits. The device supports sampling rates up to 96 kHz and operates within a supply voltage range of 1.1 V to 3.6 V. It utilizes serial I2C and I2S interfaces for control and data transmission. The component is housed in a 32-pin VQFN package measuring 5 mm x 5 mm, suitable for surface-mount installation. It functions reliably across an operating temperature range from -40°C to +85°C.

Codecs Feature Summary

• Integrates dual ADCs and DACs for high-fidelity stereo audio processing
• Supports low-voltage operation for extended battery life in portable devices
• Includes programmable analog front-end with integrated microphone bias

Codecs Applications

• Portable media players and MP3 devices
• Mobile phones and smartphones
• Voice over IP (VoIP) handsets
• Digital voice recorders

Codecs Procurement Notes

Verify the specific suffix IRHBT confirms the VQFN-32 package and industrial temperature grade when sourcing. Ensure compatibility with system power rails, as the analog supply requires 1.1 V to 3.6 V while digital logic levels must align with the host processor. Confirm moisture sensitivity handling procedures are followed during assembly to prevent package damage.

Codecs Selection Notes

Select this component when a compact stereo codec with low power consumption is required for mobile or handheld electronics. It is appropriate for designs needing 24-bit resolution at sample rates up to 96 kHz. Consider alternative models if higher channel counts or automotive qualification (AEC-Q100) are mandatory, as this part is specified for commercial/industrial environments only.

Codecs Part Context

This part belongs to the TLV320AIC31 family of low-power audio CODECs from Texas Instruments. It serves as a specialized interface between analog audio signals and digital processors. The device integrates necessary analog circuits to reduce external component count, making it distinct from general-purpose audio amplifiers or standalone ADC/DAC chips.

Codecs Replacement Considerations

The TLV320AIC3101IRHBR is a documented substitute within the same product family. Verify pinout compatibility and software register settings before substitution, as minor functional differences may exist between revisions.
