TLV320DAC3100IRHBT

ADCs/DACs - Special Purpose Overview

The TLV320DAC3100IRHBT is a low-power stereo audio DAC featuring a mono Class-D speaker amplifier, manufactured by Texas Instruments. It supports 24-bit resolution and sample rates from 8 kHz to 192 kHz with a typical SNR of 95 dB. The device integrates 25 programmable digital processing blocks for filters and DRC, alongside a digital sine-wave generator. Power supplies include AVDD (2.7 V–3.6 V), DVDD (1.65 V–1.95 V), IOVDD (1.1 V–3.6 V), and SPKVDD (2.7 V–5.5 V). It utilizes I2C control and serial audio interfaces in a 32-pin VQFN package.

ADCs/DACs - Special Purpose Feature Summary

• Stereo audio DAC with 95-dB SNR and integrated mono Class-D BTL speaker driver capable of 2.5 W into 4-Ω loads
• 25 built-in programmable digital audio processing blocks providing biquad/FIR filters, dynamic range compression, and digital mixing
• Supports multiple audio interfaces including I2S, left/right justified, DSP, and TDM modes with flexible clock generation via programmable PLL
• Includes digital sine-wave generator for beeps/key clicks, microphone bias, headphone detection, and full power-down control

ADCs/DACs - Special Purpose Applications

• Portable audio devices
• Mobile internet devices
• E-book readers

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix IRHBT corresponds to the 32-VQFN package and tape-and-reel packaging configuration. Confirm that the analog supply voltage requirements align with the target system design, as the device requires distinct voltage rails for analog, digital core, and Class-D amplifier sections. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a combined stereo DAC and mono speaker amplifier solution is required to minimize board space. The integrated miniDSP capabilities allow for equalization and bass enhancement without external processors. Verify that the input voltage levels for the digital interface match the host controller's IOVDD supply range between 1.1 V and 3.6 V.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320DAC31xx series of low-power audio DACs from Texas Instruments. The family includes variants such as the TLV320DAC3101, which features a stereo Class-D amplifier instead of mono. The IRHBT designation indicates the commercial temperature range (-40°C to +85°C) and the specific reel packaging format used for surface-mount assembly.

ADCs/DACs - Special Purpose Replacement Considerations

The TLV320DAC3101 serves as a direct functional alternative if a stereo Class-D amplifier output is required instead of mono. For applications requiring only the DAC functionality without the amplifier, the TLV320ADC3100 series may be considered, though pinouts and feature sets differ significantly.
