PCM2706CPJT

Audio Special Purpose Overview

The PCM2706CPJT is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 16-bit resolution and supports a sampling rate of 48 kHz. The device utilizes a Delta-Sigma architecture and provides two DAC channels with bipolar outputs. It operates on a single power supply ranging from 3.3 V to 5 V, consuming approximately 23 mA of working current. The component is housed in a 32-pin TQFP package and offers a dynamic range of 98 dB. It supports I2S and USB interfaces for digital audio input.

Audio Special Purpose Feature Summary

• 16-bit resolution with 48 kHz sampling rate
• Stereo output with 98 dB dynamic range
• Supports I2S and USB digital interfaces
• Operates on 3.3 V or 5 V single supply

Audio Special Purpose Applications

• USB audio peripherals
• I2S-based audio systems
• Consumer audio equipment

Audio Special Purpose Procurement Notes

Verify the specific suffix 'CPJT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure compatibility with the required PCB footprint for the 32-TQFP package during procurement planning.

Audio Special Purpose Selection Notes

Select this component when a stereo DAC with integrated USB or I2S interface capability is required. Compare the 98 dB SNR and 16-bit resolution against system noise floor requirements. Verify that the 3.3 V/5 V operating voltage aligns with the target system's power rails.

Audio Special Purpose Part Context

This part belongs to the PCM2706C series of audio DACs. It is functionally related to variants such as the PCM2706CPJTR and PCM2706PJT, which share similar core specifications but may differ in packaging format or reel quantity.

Audio Special Purpose Replacement Considerations

The PCM2706CPJTR is a direct functional alternative within the same series, typically differing only in packaging type (reel vs. tray). Other family members like the PCM2704C offer similar performance with different pin counts.
