PCM1739E

ADCs/DACs - Special Purpose Overview

The PCM1739E 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 192 kHz. The device utilizes an enhanced multi-bit delta-sigma architecture with a 64x oversampling digital filter. It operates on a single 5V analog supply and a separate 3.3V or 5V digital supply, drawing low power. Key electrical specifications include a signal-to-noise ratio of 108 dB and total harmonic distortion plus noise of 0.0004%. The component is housed in a 28-pin SSOP package.
