Overview
The TLV320AIC3120IRHBR is a low-power, highly integrated mono audio codec manufactured by Texas Instruments. It features a 24-bit mono DAC and a mono ADC with a maximum sampling rate of 192 kHz. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports serial I2C control interfaces. Designed for surface-mount applications, it is housed in a 32-VQFN package suitable for temperatures ranging from -40°C to +85°C.
Feature Summary
- Integrates embedded miniDSP capabilities for advanced audio processing
- Includes a built-in mono Class-D speaker amplifier
- Supports high-resolution 24-bit audio conversion at up to 192 kHz
Applications
- Portable audio players
- VoIP handsets
- Smart home audio devices
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when reviewing distributor listings. Confirm that the component matches the 32-VQFN footprint and pinout requirements for your PCB layout. Ensure the selected variant aligns with the required mono channel configuration rather than stereo alternatives within the same family.
Selection Notes
Select this component when a compact solution combining an audio codec with a direct-drive speaker amplifier is required. It is appropriate for designs needing embedded digital signal processing without external microcontrollers. Consider the power consumption constraints and the need for mono output channels before finalizing the design.
Part Context
This part belongs to the TLV320AIC31xx series of low-power audio codecs from Texas Instruments. It shares architectural similarities with other members like the TLV320AIC3100 but differs in channel configuration and integrated amplifier presence. The series targets mobile and portable electronics requiring high-quality audio in minimal space.
Replacement Considerations
The TLV320AIC3101IRHBR is a documented substitute within the same product family. Verify compatibility regarding mono versus stereo channel requirements and the presence or absence of an integrated speaker amplifier before swapping components.
