TLV320DAC23PWR

ADCs/DACs - Special Purpose Overview

The TLV320DAC23 is a high-performance stereo digital-to-analog converter (DAC) featuring multibit sigma-delta technology with integrated oversampling digital interpolation filters. It supports data word lengths of 16, 20, 24, and 32 bits at sampling rates from 8 kHz to 96 kHz. The device achieves up to 100 dBA SNR at audio sample rates up to 96 kHz. Power consumption is less than 19 mW during playback. Integrated analog features include stereo line inputs with an analog bypass path and a stereo headphone amplifier capable of delivering 30 mW per channel into 32 Ω. The component operates with 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.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific package variant required for the design, as the TLV320DAC23 is available in 32-Pin MicroStar Junior (GQE), 28-Pin TSSOP (PW), and 28-Pin QFN (RHD). Confirm the operating temperature range, selecting between the commercial grade (-10°C to 70°C) or industrial grade (-40°C to 85°C). Ensure that the ordering suffix matches the desired package and temperature rating exactly.

ADCs/DACs - Special Purpose Selection Notes

Select the TLV320DAC23 when designing portable digital audio applications requiring low power consumption and high-quality stereo playback. The device is optimized for use with TI C54x DSPs and USB interfaces, supporting unique oversample rates of 250 fs and 272 fs to simplify clocking from a single 12-MHz crystal. Ensure the system design accommodates the separate analog (AVDD/HPVDD) and digital (DVDD/BVDD) supply requirements.

ADCs/DACs - Special Purpose Part Context

The TLV320DAC23 is part of Texas Instruments' digital audio products portfolio, specifically designed for portable audio applications. It complements other components in the ecosystem by providing glueless interface compatibility with TI McBSPs. The device utilizes Texas Instruments' proprietary MicroStar Junior packaging to minimize board area, making it suitable for space-constrained portable designs.
