TLV320DAC23PW

ADCs/DACs - Special Purpose Overview

The TLV320DAC23PW is a low-power stereo digital-to-analog converter (DAC) with an integrated headphone amplifier manufactured by Texas Instruments. It features two DAC channels and supports data word lengths of 16, 20, 24, and 32 bits at sampling rates up to 96 kHz. The device operates on a single supply voltage ranging from 2.7 V to 3.6 V for the analog section and 1.42 V to 3.6 V for the digital section. It provides high audio performance with a signal-to-noise ratio of 90 dB for the DAC and includes programmable gain control. The component is housed in a 28-pin TSSOP package and functions within a temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PW' confirms the 28-pin TSSOP package variant. Confirm current availability status as this component may be discontinued or superseded by newer generations in the TLV320 family. Ensure compatibility with existing system power rails and interface protocols before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a dedicated stereo DAC with integrated output amplification is required for portable applications. It is suitable for designs needing low power consumption during playback and standby modes. Verify that the host processor supports the required serial interface protocol and data word lengths for seamless integration.

ADCs/DACs - Special Purpose Part Context

The TLV320DAC23PW belongs to the TLV320DAC23 series of low-power stereo DACs from Texas Instruments. This series is designed for battery-powered consumer electronics requiring high-quality audio reproduction with minimal power draw. It complements other components in the TLV320 family, such as CODECs, by providing specialized digital-to-analog conversion capabilities.

ADCs/DACs - Special Purpose Replacement Considerations

Check for direct replacements within the TLV320DAC23 family, such as the TLV320DAC23IPW or TLV320DAC23IPWG4, which share similar specifications and pinouts. Evaluate newer Texas Instruments audio DACs if the current part is obsolete, ensuring pin compatibility and feature parity.
