TLV320AIC3111IRHBR

Overview

The TLV320AIC3111IRHBR is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable audio and telephony applications. It features a 32-bit resolution with a maximum conversion rate of 192 kHz. The device integrates one analog-to-digital converter (ADC) and two digital-to-analog converters (DAC). It operates within a supply voltage range of 2.7 V to 3.6 V and supports serial I2C interface control. The component exhibits a signal-to-noise ratio of 91 dB for the ADC and 95 dB for the DAC, with total harmonic distortion plus noise of -85 dB for the ADC and -82 dB for the DAC. It is housed in a VQFN-32 package suitable for surface mount technology.

Feature Summary

• Stereo audio processing capability with integrated ADC and dual DAC channels
• High-resolution digital audio support up to 32 bits and 192 kHz sampling rates
• Low-power architecture optimized for battery-operated portable devices

Applications

• Portable audio players and media devices
• Telephony handsets and communication modules
• Embedded audio systems in consumer electronics

Procurement Notes

Verify the specific suffix IRHBR indicates the reel packaging variant when sourcing. Confirm that the operating voltage requirements align with the 2.7 V to 3.6 V specification for your system design. Ensure compatibility with the VQFN-32 footprint during PCB layout. Check for moisture sensitivity level requirements if storage conditions are not controlled. Validate that the I2C interface matches your controller's communication protocol.

Selection Notes

Select this component when high-fidelity stereo audio is required alongside low power consumption. The 32-bit resolution and 192 kHz rate support high-quality audio playback and recording. Consider the single ADC configuration if input channel count is limited. The VQFN-32 package offers a compact solution for space-constrained designs. Ensure the system can provide the necessary 2.7 V to 3.6 V supply rails.

Part Context

This part belongs to the TLV320AIC3111 series of low-power stereo audio codecs from Texas Instruments. It shares architectural similarities with other members like the TLV320AIC3100 and TLV320AIC3101 but offers distinct performance metrics such as 32-bit resolution and 192 kHz support. The series is targeted at portable audio markets requiring efficient power management and high audio quality.

Replacement Considerations

The TLV320AIC3111IRHBT is a tape-and-reel alternative within the same family. Verify pinout and electrical specifications before substitution. Other series members like TLV320AIC3101 offer different resolutions and may require firmware adjustments.
