TLV320DAC23IPWR

ADCs/DACs - Special Purpose Overview

The TLV320DAC23IPWR is a high-performance stereo digital-to-analog converter (DAC) from Texas Instruments, designed for portable audio applications. It utilizes multibit sigma-delta technology with integrated oversampling digital interpolation filters. The device supports data word lengths of 16, 20, 24, and 32 bits at sampling rates ranging from 8 kHz to 96 kHz. Key electrical specifications include a signal-to-noise ratio (SNR) of up to 100 dBA at 48 kHz and power consumption of less than 19 mW during playback. It features an integrated headphone amplifier capable of delivering 30 mW per channel into a 32-ohm load.

ADCs/DACs - Special Purpose Feature Summary

• High-performance stereo DAC with 100-dB SNR using multibit sigma-delta modulation
• Integrated stereo line inputs, line outputs, and headphone amplifier with analog volume control
• Software-controlled via SPI or 2-wire compatible serial interfaces
• Flexible power management with standby (<150 µW) and power-down (<15 µW) modes

ADCs/DACs - Special Purpose Applications

• Portable digital audio players
• MP3 players
• Solid-state audio recorders

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'R' suffix indicates tape-and-reel packaging when sourcing this component. Confirm that the specific revision matches the required operating temperature range (-40°C to 85°C). Ensure compatibility with the host system's voltage levels, specifically the 1.42 V to 3.6 V digital core supply and 2.7 V to 3.6 V analog supplies.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring low-power stereo DAC functionality with integrated headphone driving capabilities. It is suitable for systems utilizing TI C54x DSPs due to optimized over-sample rates (250 fs and 272 fs) that allow a single 12-MHz crystal to clock multiple peripherals. Ensure the application can accommodate the 28-pin TSSOP package or the smaller MicroStar Junior/QFN options if space is constrained.

ADCs/DACs - Special Purpose Part Context

The TLV320DAC23 series includes variants such as the IPW (TSSOP) and IRHD (QFN) packages. The IPWR designation specifically refers to the industrial temperature grade (-40°C to 85°C) in the Tape and Reel format. This part serves as the digital-to-analog conversion stage in audio chains, often paired with external ADCs or used in systems where only playback is required.
