PCM1770RGAR

ADCs/DACs - Special Purpose Overview

The PCM1770RGAR 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 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 0.04%. It integrates a headphone amplifier and utilizes an SPI interface for control. The component is housed in a VQFNP-20 package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'RGAR' against the official datasheet to confirm the reel packaging quantity and tape specifications. Ensure the voltage domain matches the 1.6 V to 3.6 V requirement. Check for RoHS compliance status as indicated in the manufacturer's documentation.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a low-power stereo DAC with an integrated headphone amp is required. Compare THD+N of 0.04% against system noise floor requirements. Verify that the VQFNP-20 package footprint fits the PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1770 series of low-power audio DACs. It shares core specifications with the PCM1770PWR but differs in package type and packaging format. The series is designed for battery-operated applications requiring high audio fidelity with minimal power draw.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1770PWR is a pin-compatible alternative in a TSSOP-16 package. Verify package dimensions and thermal characteristics before substitution.
