PCM1772PWG4

ADCs/DACs - Special Purpose Overview

The PCM1772PWG4 is a low-voltage, low-power stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 48 kHz. The device integrates a lineout amplifier, eliminating the need for external output stages in many applications. It operates on a single power supply ranging from 1.6 V to 3.6 V with a typical operating current of 2.5 mA. Key performance metrics include a signal-to-noise ratio (SNR) of 98 dB and a total harmonic distortion plus noise (THD+N) of 0.007%. The component utilizes an SPI interface for control and is housed in a TSSOP-16 package.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit stereo DAC with integrated lineout amplifier
• Low power consumption: 2.5 mA operating current at 3.3 V
• High audio performance: 98 dB SNR and 0.007% THD+N
• Single-supply operation from 1.6 V to 3.6 V

ADCs/DACs - Special Purpose Applications

• Portable audio players and MP3 devices
• Home theater systems and AV receivers
• Computer sound cards and multimedia peripherals

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix 'G4' indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the package type is TSSOP-16 for PCB layout compatibility. Ensure the design supports the specified 1.6 V to 3.6 V single-supply voltage range and SPI communication protocol.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a low-power stereo DAC with an integrated output amplifier is required. It is suitable for battery-operated devices due to its low voltage operation and minimal current draw. Compare against the PCM1770 series if a headphone amplifier is needed instead of a lineout driver, noting differences in THD+N specifications.

ADCs/DACs - Special Purpose Part Context

The PCM1772PWG4 belongs to the PCM1772 family of audio DACs from Texas Instruments. It is the lead-free, RoHS-compliant version of the PCM1772PW. This part is designed for high-fidelity audio reproduction in compact consumer electronics, offering a balance between power efficiency and audio quality.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1772PW is the non-RoHS equivalent. For pin-compatible alternatives with similar features, consider the PCM1770 series, though it includes a headphone amplifier rather than a lineout amp.
