TLV320AIC31IRHBR

Codecs Overview

The TLV320AIC31IRHBR is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable audio and telephony applications. It features a 24-bit resolution with a maximum sampling rate of 48 kHz. The device integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs). It operates within a supply voltage range of 1.65 V to 3.6 V and supports serial interface communication. The component is housed in a 32-pin VQFN package and functions reliably across an operating temperature range of -40°C to +85°C.

Codecs Feature Summary

• Integrates stereo ADC and DAC channels for high-fidelity audio processing
• Supports low-power operation suitable for battery-powered portable devices
• Includes programmable miniDSP capabilities for audio signal conditioning

Codecs Applications

• Portable audio players and media devices
• Telephony handsets and VoIP equipment
• Voice recognition systems and smart speakers

Codecs Procurement Notes

Verify the specific suffix 'IRHBR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system power rails and interface protocols before integration. Cross-reference the part number with official Texas Instruments documentation to validate manufacturing status and environmental compliance details such as RoHS standards.

Codecs Selection Notes

Select this component when a stereo codec with integrated DSP functionality is required for space-constrained designs. The VQFN-32 package offers a compact footprint compared to larger QFP options. Consider the 24-bit resolution and 48 kHz sampling limit when evaluating audio quality requirements against higher-performance alternatives in the TLV320AIC31xx family.

Codecs Part Context

This part belongs to the TLV320AIC31 series of low-power stereo audio codecs from Texas Instruments. It shares architectural similarities with variants like the TLV320AIC3101 but may differ in specific feature sets or packaging configurations. The series is engineered to provide cost-effective audio solutions for consumer electronics requiring balanced performance and power efficiency.

Codecs Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as the TLV320AIC3101IRHBR, ensuring functional equivalence in ADC/DAC counts and interface types. Verify that any alternative maintains the same 32-VQFN package dimensions and thermal characteristics.
