TLV320DAC23IRHD

ADCs/DACs - Special Purpose Overview

The TLV320DAC23IRHD is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features two DAC channels with a 24-bit resolution and supports sampling rates up to 96 kHz. The device operates on a single power supply ranging from 2.7 V to 3.6 V. Key performance metrics include a signal-to-noise ratio of 97 dB and a total harmonic distortion plus noise of 0.0079%. It utilizes an SPI interface for control and is housed in a 28-pin VQFN package, designed for surface-mount installation within an operating temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Stereo 24-bit DAC with integrated headphone amplifier
• High audio fidelity: 97 dB SNR and 0.0079% THD+N
• SPI serial interface for digital control
• Low-power operation with 2.7 V to 3.6 V supply range

ADCs/DACs - Special Purpose Applications

• Portable audio players and MP3 devices
• Mobile phones and smartphones
• Digital voice recorders
• Personal navigation systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'IRHD' corresponds to the 28-pin VQFN package and commercial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before procurement. Ensure ESD handling protocols are followed due to the moisture sensitivity and small form factor of the VQFN package.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a low-power stereo DAC with an integrated headphone amplifier is required. It is suitable for applications needing high audio quality (97 dB SNR) with minimal external components. Compare against the TLV320AIC23 if an analog-to-digital converter (ADC) input is also necessary, as the DAC23 variant lacks ADC functionality.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320DAC2x series of low-power audio DACs from Texas Instruments. It is functionally related to the TLV320AIC23, which adds ADC capabilities to the same core architecture. The IRHD suffix denotes the specific tape-and-reel packaging and thermal grade for this surface-mount device.

ADCs/DACs - Special Purpose Replacement Considerations

The TLV320AIC23IRHD offers pin-compatible functionality but includes additional ADC channels. Verify that the extra ADC resources do not cause interface conflicts and that the power consumption profiles match the system requirements.
