PCM1772PWR

ADCs/DACs - Special Purpose Overview

The PCM1772PWR is a 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 and operates on a single power supply ranging from 1.6 V to 3.6 V. Key performance metrics include a signal-to-noise ratio of 98 dB and a total harmonic distortion plus noise of 0.007%. It utilizes an SPI interface for control and is housed in a VQFNP-20 package, designed for low-voltage and low-power applications.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 2-channel stereo output
• Integrated lineout amplifier
• Low power consumption with 2.5 mA operating current
• SPI serial interface compatibility

ADCs/DACs - Special Purpose Applications

• Portable audio players
• Mobile communication devices
• Low-voltage consumer electronics

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 or VQFNP-20 package variant as listed in official distributor catalogs. Confirm RoHS compliance status through the manufacturer's datasheet before integration. Ensure the ordering part number matches the exact pin configuration required for the target PCB layout.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a low-voltage operation between 1.6 V and 3.6 V is required. The integrated lineout amplifier makes it suitable for direct driving of passive loads without additional external amplification stages. Compare SNR and THD+N specifications against other PCM17xx series variants if higher fidelity or different packaging options are needed.

ADCs/DACs - Special Purpose Part Context

The PCM1772 belongs to the PCM177x family of low-voltage, low-power stereo DACs from Texas Instruments. This series is engineered for battery-operated portable equipment where power efficiency and small form factor are critical design constraints.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1770PWR is a related model within the same family but includes a headphone amplifier instead of a lineout amplifier. Verify functional equivalence regarding output stage requirements before substitution.
