TLV320DAC23RHDR

ADCs/DACs - Special Purpose Overview

The TLV320DAC23RHDR is a stereo audio digital-to-analog converter manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates from 8 kHz to 96 kHz. The device operates within a supply voltage range of 2.7 V to 3.6 V and utilizes an SPI serial interface for control. Housed in a 28-pin TSSOP package, it includes integrated headphone amplifiers. Key performance metrics include a signal-to-noise ratio of 95 dB and total harmonic distortion plus noise of -85 dB.

ADCs/DACs - Special Purpose Feature Summary

• Integrates high-performance stereo DACs with multibit sigma-delta modulation technology
• Includes dedicated headphone amplifiers suitable for direct speaker or headphone driving
• Supports standard serial communication protocols including I2C and SPI for configuration

ADCs/DACs - Special Purpose Applications

• Portable audio players and media devices
• Mobile phones and smartphones
• Digital voice recorders
• Consumer electronics requiring low-power audio playback

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix RHDR confirms the tape and reel packaging format and the TSSOP-28 package variant. Ensure compatibility with the target system's 2.7 V to 3.6 V power domain. Confirm that the SPI/I2C interface levels match the host controller logic voltages. Check for RoHS compliance documentation if required by regional regulations.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a compact stereo DAC with integrated output drivers is required. It is suitable for applications prioritizing low power consumption and minimal external component count. Consider alternative models if higher sampling rates beyond 96 kHz or different package footprints are necessary. Evaluate thermal dissipation requirements based on the TSSOP-28 package constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320DAC23 series of audio codecs from Texas Instruments. It is designed as a complete solution for stereo audio playback in portable devices. The series emphasizes integration by combining digital conversion and analog output stages into a single chip, reducing board space and design complexity compared to discrete solutions.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes may include other variants within the TLV320DAC23 family, such as TLV320DAC23IRHDR, provided the package and interface specifications remain compatible. Verify pinout and electrical characteristics before substitution.
