PCM1792ADBG4

ADCs/DACs - Special Purpose Overview

The PCM1792ADBG4 is a stereo digital-to-analog converter (DAC) from Texas Instruments, featuring a 24-bit resolution and a maximum sampling rate of 192 kHz. It utilizes an advanced segment architecture to achieve high performance metrics, including a typical signal-to-noise ratio (SNR) of 127 dB and a total harmonic distortion plus noise (THD+N) of 0.001%. The device operates on a single 5V supply, with voltage limits ranging from 4.75 V to 5.25 V. It supports I2C and SPI control interfaces for software configuration and is housed in a 28-pin SSOP package suitable for surface-mount technology.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the SSOP-28 package dimensions and pinout against the official datasheet before integration. Ensure the design supports the required 5V analog and digital power supplies within the specified 4.75 V to 5.25 V range.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 24-bit stereo DAC with 192 kHz capability is required. Compare SNR and THD+N values against other models in the PCM179x series if higher dynamic range is needed. Verify that the I2C/SPI interface compatibility matches the host microcontroller. Consider the SSOP-28 package size constraints relative to the PCB layout.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1792A series, which are characterized by their high-performance stereo DAC capabilities. The 'ADB' prefix typically denotes the SSOP-28 package variant, while 'G4' signifies environmental compliance. It is distinct from the PCM1792 without the 'A' suffix, which may have different electrical characteristics or revision levels.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1792DBRG4 is a compatible alternative within the same family, offering identical core specifications. Verify pin-to-pin compatibility and register mapping before substitution. Other members of the PCM179x series may require schematic adjustments due to differing pinouts or control logic.
