TLV320DAC32IRHBRG4

ADCs/DACs - Special Purpose Overview

The TLV320DAC32IRHBRG4 is a low-power stereo audio DAC from Texas Instruments, designed for portable devices. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device includes two converters with four output channels, utilizing an I2C interface for control. It operates within a supply voltage range of 1.1 V to 3.6 V, consuming approximately 18 mW at 48 kHz playback. Key performance metrics include a signal-to-noise ratio of 95 dB and THD+N of 0.02%. Packaged in a 32-VQFN, it functions between -40°C and +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Integrates high-fidelity digital-to-analog conversion with programmable audio effects such as bass, treble, and equalization.
• Features flexible analog input and output configurations, including analog bypass paths and dedicated headphone/speaker drivers.
• Supports multiple digital audio serial interfaces including I2S, left/right-aligned, DSP, and TDM modes.
• Incorporates internal power management capabilities allowing single-supply operation via an integrated LDO regulator.

ADCs/DACs - Special Purpose Applications

• Smartphones and mobile communication devices
• Personal Digital Assistants (PDAs)
• Portable computing and entertainment systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's current product status, as this may indicate lead-free compliance or specific packaging variations compared to standard versions. Confirm that the 32-VQFN package dimensions match the target PCB footprint requirements. Ensure the I2C address configuration aligns with the system bus architecture to prevent address conflicts with other peripherals.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a dedicated stereo DAC is required rather than a full codec, as it lacks an integrated ADC. Evaluate the 1.1 V to 3.6 V supply range compatibility with the host processor's I/O voltage levels. Consider the 18 mW power consumption figure for battery life calculations during active playback. Verify that the 95 dB SNR meets the audio quality specifications for the intended application environment.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320DAC32 series, which focuses on low-power audio solutions for space-constrained portable electronics. It serves as a specialized digital-to-analog converter distinct from the TLV320AIC series codecs, offering simplified integration for systems requiring only audio output functionality without recording capabilities.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes include the TLV320DAC32IRHBT and TLV320DAC32IRHBR. These variants share identical electrical characteristics and pinouts but may differ in moisture sensitivity levels or reel packaging quantities. Verify RoHS compliance status across all candidate parts before substitution.
