TLV320AIC3110IRHBT

Overview

The TLV320AIC3110IRHBT is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable audio applications. It features a 24-bit resolution with a maximum sampling rate of 96 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 1.1 V to 3.6 V and supports serial interfaces including I2C for control and I2S/PCM for data. Encased in a 32-pin VQFN package, it functions between -40°C and +85°C, offering high signal-to-noise ratios of 92 dB for ADC and 100 dB for DAC.

Feature Summary

• Integrates dual ADCs and dual DACs for complete stereo audio processing
• Supports multiple serial digital audio interfaces including I2S and PCM
• Operates on a wide single-supply voltage range from 1.1 V to 3.6 V

Applications

• Portable media players and MP3 devices
• Mobile handsets and smartphones
• Digital voice recorders
• Portable navigation systems

Procurement Notes

Verify the specific suffix IRHBT confirms the VQFN-32 package and industrial temperature grade. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before procurement. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the full part number against the latest Texas Instruments product selection guide to avoid obsolete variants.

Selection Notes

Select this component when a stereo codec with 24-bit resolution and 96 kHz sampling is required for battery-powered devices. It is suitable for designs needing integrated analog front-end capabilities without external amplifiers. Consider the VQFN-32 footprint for space-constrained PCB layouts. Verify interface compatibility with the host processor's I2S or PCM controller. Evaluate power consumption requirements against the 1.1 V to 3.6 V operating range.

Part Context

This part belongs to the TLV320AIC31xx series of low-power audio codecs from Texas Instruments. The series is optimized for mobile and portable consumer electronics requiring high audio quality with minimal power draw. The AIC3110 variant specifically targets stereo applications with integrated line-in and headphone-out drivers. It shares architectural similarities with other members like the AIC3100 but offers distinct pin configurations and feature sets tailored for specific form factors.

Replacement Considerations

Direct replacements include TLV320AIC3100IRHBT and TLV320AIC3111IRHBT from the same family. Verify pin-to-pin compatibility and register map differences before substitution. Alternative packages such as WQFN may require schematic and layout modifications.
