TLV320DAC3100IRHBR

ADCs/DACs - Special Purpose Overview

The TLV320DAC3100IRHBR is a low-power stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features 24-bit resolution and supports sampling rates up to 192 kHz. The device integrates a mono Class-D speaker amplifier capable of driving loads as low as 4Ω, alongside headphone drivers. Key electrical parameters include a typical signal-to-noise ratio (SNR) of 95 dB for the DAC channels. It operates with analog supply voltages between 2.7 V and 3.6 V, digital core voltage from 1.65 V to 1.95 V, and digital I/O from 1.1 V to 3.6 V. The component is housed in a 32-pin VQFN package measuring 5 mm x 5 mm.

ADCs/DACs - Special Purpose Feature Summary

• Integrated mono Class-D speaker amplifier supporting 2.5 W into 4Ω or 1.6 W into 8Ω loads
• Built-in digital audio processing module with 25 programmable blocks including filters and dynamic range compression
• Supports multiple digital audio interfaces: I²S, Left-Justified, Right-Justified, DSP, and TDM modes
• High-performance audio conversion with 95 dB SNR and 24-bit resolution at sampling rates up to 192 kHz

ADCs/DACs - Special Purpose Applications

• Portable multimedia devices requiring integrated speaker and headphone output
• Industrial audio systems utilizing digital signal processing capabilities
• Consumer electronics needing low-power stereo DAC solutions with built-in amplification

ADCs/DACs - Special Purpose Part Context

This component belongs to the TLV320DAC3100 series, which distinguishes itself by combining high-fidelity stereo DAC functionality with a power amplifier stage. Unlike pure DACs, it simplifies board design by eliminating external amplifier components for speakers. The IRHBR suffix indicates the specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include the TLV320DAC3101, which shares the 32-VQFN package and similar interface specifications but may differ in specific amplifier power ratings or processing block configurations. Designers should verify register compatibility and thermal performance when substituting.
