TLV320DAC23IGQER

ADCs/DACs - Special Purpose Overview

The TLV320DAC23IGQER 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. It features an internal oscillator compatible with a 12-MHz crystal, enabling direct support for 44.1 kHz and 48 kHz sample rates. Key electrical specifications include a signal-to-noise ratio of up to 100 dBA at 48 kHz, analog supply voltages between 2.7 V and 3.6 V, and digital core supply voltages from 1.42 V to 3.6 V.

ADCs/DACs - Special Purpose Feature Summary

• High-Performance Stereo DAC: Achieves 100-dB SNR (A-weighted at 48 kHz) using multibit sigma-delta architecture.
• Integrated Analog Features: Includes stereo line inputs with analog bypass paths, stereo line outputs, and a headphone amplifier delivering 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.
• Software Control: Supports SPI and 2-wire compatible serial protocols for register programming and McBSP-compatible audio interfaces.

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'IG' suffix indicates the industrial temperature range (-40°C to 85°C). Confirm the 'ER' suffix corresponds to the reel packaging format as specified in the ordering information. Ensure compatibility with the MicroStar Junior package dimensions for board layout.

ADCs/DACs - Special Purpose Selection Notes

Select this component when designing space-constrained portable audio systems requiring low power consumption. The MicroStar Junior package offers a small footprint of 25 mm². Ensure the system clock requirements align with the internal oscillator capabilities or external crystal input for desired sample rates.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TLV320DAC23 family, which includes variants in TSSOP and QFN packages. The IGQER designation specifically identifies the industrial temperature grade version housed in the 32-pin MicroStar Junior package and supplied in a reel configuration.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same package and temperature range include TLV320DAC23GQE (commercial grade) or other TI audio DACs with similar pinouts and performance metrics. Verify interface compatibility and power supply requirements before substitution.
