PCM1781DBQG4

The PCM1781DBQG4 is a high-performance audio digital-to-analog converter (DAC) chip from Texas Instruments. The device integrates four stereo DACs and more features to deliver precise, high quality audio playback. The device is primarily intended for professional recording studio applications, hi-fi audio playback and consumer audio systems.

The PCM1781DBQG4 incorporates a 16-bit DAC which can be used to provide high quality audio output, support for multiple sampling frequencies, and a low noise and distortion specification. The device is designed to reduce jitter significantly and offer improved dynamic range, superior linearity and excellent signal-to-noise ratio. It also integrates a multi-channel pulse density modulation (PDM) converter which enables stereo audio and provides a high-resolution audio playback solution.

The PCM1781DBQG4 is a digital-to-analog converter that utilizes an innovative Sigma-Delta architecture to offer the best performance and audio quality. The device incorporates high resolution 24-bit DACs and supports high sample rates up to 192kHz. It features low distortion, high dynamic range and low output noise. The device also supports a wide range of audio formats such as PCM, DSD and Dolby Digital.

Sigma-Delta architecture employs cascading digital filters and modulators for high-accuracy analogue to digital conversion. This architecture is employeed in PCM1781DBQG4 allowing accurate sound reproduction. The DAC implements and oversampling, noise shaping and decimation steps and then performs digital to analog conversion.
