TLV320DAC23IPW

ADCs/DACs - Special Purpose Overview

The TLV320DAC23IPW is a low-power stereo digital-to-analog converter (DAC) with an integrated headphone amplifier, manufactured by Texas Instruments. It utilizes sigma-delta oversampling technology to deliver high-fidelity audio performance. The device features two DAC channels and supports data word lengths of 16, 20, 24, and 32 bits. It operates within a digital supply voltage range of 1.42 V to 3.6 V and an analog supply voltage range of 2.7 V to 3.6 V. The component is housed in a 28-pin TSSOP package and is rated for operation between -40°C and +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Integrated stereo headphone amplifier capable of delivering 30 mW per channel into a 32-ohm load
• Sigma-delta modulation architecture providing 100 dB SNR for the DAC section
• Low power consumption with playback mode current draw of approximately 23 mW
• Supports standard sampling rates from 8 kHz to 96 kHz

ADCs/DACs - Special Purpose Applications

• Portable digital audio players
• Mobile phones and smartphones
• Digital voice recorders
• MP3 players

ADCs/DACs - Special Purpose Part Context

This component belongs to the TLV320AIC23 family of audio codecs. While the full codec variant includes both ADC and DAC sections, the TLV320DAC23IPW specifically integrates only the DAC and headphone amplifier functions. It shares similar pinouts and control interfaces with the broader AIC23 series, allowing for design flexibility in systems requiring only digital-to-analog conversion.

ADCs/DACs - Special Purpose Replacement Considerations

The TLV320AIC23BPWG4 serves as a direct functional replacement if analog-to-digital conversion capabilities are also required. For applications needing only the DAC function, other variants within the TLV320DAC23 series, such as those in QFN packages, may offer space-saving alternatives while maintaining electrical compatibility.
