PCM1792ADBR

ADCs/DACs - Special Purpose Overview

The PCM1792ADBR 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 advanced segment architecture and includes integrated software control via I2C or SPI interfaces. Key electrical specifications include a typical signal-to-noise ratio (SNR) of 127 dB and a total harmonic distortion plus noise (THD+N) of 0.001%. It operates on a single power supply ranging from 4.75 V to 5.25 V and is housed in a 28-pin SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the design requires the specific 4.75 V to 5.25 V analog and digital power supply range. Ensure the host microcontroller supports the required I2C or SPI communication protocols for register configuration.

ADCs/DACs - Special Purpose Selection Notes

Select the PCM1792ADBR when high dynamic range and low distortion are critical requirements. Compare against the PCM1793 series if lower cost is prioritized over the highest SNR performance. Verify compatibility with the system's digital input format, as this component accepts serial binary data. Consider the SSOP-28 package dimensions for PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

This component belongs to the PCM1792A family of stereo DACs from Texas Instruments. It is functionally similar to the PCM1792ADB but differs in packaging and reel configuration. The 'A' variant denotes the specific silicon revision or performance bin associated with the 127 dB SNR specification.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1792ADB is a pin-compatible alternative with identical electrical characteristics but may differ in shipping packaging. The PCM1793 series offers similar functionality with potentially different performance trade-offs regarding SNR and gain error.
