PCM2704DBG4

ADCs/DACs - Special Purpose Overview

The PCM2704DBG4 is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It integrates a USB interface to receive digital audio data, which it converts into analog signals for playback. The device features a single-ended headphone output and an S/PDIF digital output. It operates on a single power supply ranging from 3 V to 5.25 V. The component utilizes a delta-sigma architecture with a maximum sampling rate of 48 kHz and provides 16-bit resolution. It is housed in a 28-pin SSOP package.

ADCs/DACs - Special Purpose Part Context

The PCM2704DBG4 is the lead-free, RoHS-compliant variant of the PCM2704DB. The 'G4' suffix indicates compliance with environmental standards while maintaining identical electrical and functional specifications to the standard PCM2704DB part within the PCM2704 family.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM2704DB serves as the direct non-RoHS equivalent. For pin-compatible alternatives with similar functionality, the PCM2704CDB may be considered, though verification of specific package and electrical tolerances against the original design requirements is necessary.
