TLV320AIC3120IRHBT

Overview

The TLV320AIC3120IRHBT is a low-power mono audio codec manufactured by Texas Instruments. It features a 32-bit resolution and supports sample rates from 8 kHz to 192 kHz for both the analog-to-digital converter (ADC) and digital-to-analog converter (DAC). The device operates within a supply voltage range of 2.7 V to 3.6 V and includes an embedded miniDSP. It utilizes serial I2C interfaces for control and communication. The component is housed in a 32-pin VQFN package measuring 5x5 mm, designed for surface mount installation.

Feature Summary

• Integrates a mono audio DAC with high signal-to-noise ratio performance
• Includes a mono audio ADC optimized for clear input capture
• Supports flexible sampling rates ranging from 8 kHz to 192 kHz
• Features embedded miniDSP capabilities for audio processing

Applications

• Portable consumer electronics requiring low power consumption
• Voice recording devices and dictaphones
• Hands-free telecommunication systems
• Embedded audio interfaces in IoT devices

Procurement Notes

Verify the specific suffix 'RHBT' corresponds to the tape and reel packaging configuration when ordering. Confirm that the operating voltage requirements align with the 2.7 V to 3.6 V specification. Ensure compatibility with the 32-VQFN footprint during PCB layout. Cross-reference the datasheet revision to confirm interface timing parameters match your system design.

Selection Notes

Select this component for applications requiring a single-channel audio solution with integrated digital signal processing. It is suitable where space constraints favor the compact 5x5 mm VQFN package. Consider the 192 kHz maximum sample rate if high-fidelity audio reproduction is necessary. Verify that the I2C control interface integrates seamlessly with the host microcontroller.

Part Context

This part belongs to the TLV320AIC3120 family of low-power audio codecs. It serves as a specialized solution for mono audio paths, distinguishing itself from stereo counterparts by integrating only one ADC and one DAC channel. The inclusion of miniDSP allows for equalization and filtering without external processors, reducing system complexity compared to basic codec alternatives.
