PCM1792DBG4

ADCs/DACs - Special Purpose Overview

The PCM1792ADBG4 is a stereo digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 192 kHz using an advanced segment architecture. The device integrates two DAC channels within a 28-pin SSOP package. 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 analog and digital power supply ranging from 4.75 V to 5.25 V, with a functional temperature range of -25°C to +85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type is SSOP-28 and check for any specific ordering suffixes that may affect pinout or functionality. Ensure the source document explicitly lists the PCM1792ADBG4 part number to avoid confusion with similar variants like the PCM1792DBR.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a stereo DAC with 24-bit resolution and 192 kHz support is required. It is suitable for applications demanding low distortion and high dynamic range. Consider the SSOP-28 package size and the need for software-controlled configuration via I2C or SPI. Verify power supply requirements match the 4.75 V to 5.25 V range.

ADCs/DACs - Special Purpose Part Context

The PCM1792ADBG4 belongs to the PCM1792A series of audio DACs from Texas Instruments. This series is designed for high-performance stereo audio applications. The 'DBG4' suffix typically denotes the package style (SSOP) and environmental compliance (Lead-Free/RoHS). It is distinct from other PCM179x family members which may have different pinouts or feature sets.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same family include the PCM1792ADB or PCM1792DBR, provided the package and compliance requirements are met. Verify compatibility with existing PCB footprints and software configurations before substitution.
