DSD1794ADBR

ADCs/DACs - Special Purpose Overview

The DSD1794ADBR is a stereo audio digital-to-analog converter (DAC) manufactured by Burr-Brown, now part of Texas Instruments. It features 24-bit resolution and supports sampling rates up to 192 kHz using an advanced segment architecture. The device integrates two DAC channels for left and right audio outputs. It operates with a single 5V analog supply and a separate 3.3V digital supply. Key electrical specifications include a dynamic range of 113 dB and a total harmonic distortion plus noise (THD+N) of 0.001%. The component utilizes a serial interface for data input and control, housed in a 28-pin SSOP package.

ADCs/DACs - Special Purpose Part Context

The DSD1794ADB series belongs to Burr-Brown's high-performance audio DAC lineup, acquired by Texas Instruments. This specific part number denotes the tape-and-reel version of the DSD1794ADB, facilitating automated surface-mount assembly. It shares architectural similarities with other members like the PCM1794A and DSD1791, focusing on high-end audio reproduction through precise digital-to-analog conversion.

ADCs/DACs - Special Purpose Replacement Considerations

Compatible alternatives within the same family include the DSD1791 and PCM1794A. When substituting, verify pin compatibility and power supply requirements (5V analog, 3.3V digital). Ensure the replacement supports the required input format (PCM/DSD) and meets the necessary SNR and THD+N specifications for the target application.
