TLV320DAC23GQER

ADCs/DACs - Special Purpose Overview

The TLV320DAC23GQER 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 with sampling frequencies 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 total harmonic distortion (THD) of -80 dB. It operates with a digital supply voltage between 1.42 V and 3.6 V, and an analog supply voltage between 2.7 V and 3.6 V.

ADCs/DACs - Special Purpose Feature Summary

• High-Performance Stereo DAC: Features a second-order multibit sigma-delta architecture delivering up to 100 dBA SNR and -80 dB THD.
• Integrated Analog Functionality: Includes stereo line inputs/outputs, an analog bypass path, and a headphone amplifier capable of 30 mW into 32 Ω.
• Flexible Power Management: Consumes less than 19 mW during playback, with standby power under 150 µW and power-down consumption under 15 µW.
• Compact Packaging: Available in the 32-pin MicroStar Junior package (GQE), occupying only 25 mm² of board area.

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'GQER' against the manufacturer's current documentation to confirm the reel packaging format and any associated handling requirements. Ensure compliance with export regulations if applicable, as some TI products may require additional documentation for international shipping.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring low power consumption and small form factor. Ensure the system clock configuration matches the required sample rates, as the device supports unique oversampling rates (250 fs and 272 fs) optimized for specific DSP interfaces. Verify that the digital core voltage (DVDD) range of 1.42 V to 3.6 V aligns with the host processor logic levels.

ADCs/DACs - Special Purpose Part Context

The TLV320DAC23 belongs to Texas Instruments' legacy digital audio product line, originally published in February 2004. It is part of a family including variants like the TLV320DAC23PW and TLV320DAC23IRHD, distinguished primarily by package type and operating temperature range. The GQE package denotes the 32-pin MicroStar Junior variant suitable for space-constrained portable devices.
