PCM1680DBQG4

ADCs/DACs - Special Purpose Overview

The PCM1680DBQG4 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 using an enhanced multilevel delta-sigma modulation architecture. The device operates on a single power supply ranging from 4.5 V to 5.5 V, with a typical operating current of 30 mA. Key performance metrics include a signal-to-noise ratio (SNR) of 106 dB and a total harmonic distortion plus noise (THD+N) of 0.002%. It utilizes a serial 3-wire interface for control and is housed in a 16-pin SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the G4 suffix indicates RoHS compliance and green material status as per Texas Instruments standards. Confirm the SSOP-16 package dimensions against PCB footprint requirements. Ensure the serial interface timing matches the host controller specifications before integration.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-resolution audio conversion with low power consumption. Compare SNR and THD+N specifications against competing DACs if ultra-low distortion is critical. Verify that the 3-wire serial interface is compatible with the system's microcontroller or DSP.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1680 family of audio DACs. The DBQG4 designation specifies the SSOP-16 package, industrial temperature range (-25°C to +85°C), and lead-free/RoHS-compliant construction. It serves as a direct replacement for non-G4 variants within the same functional family.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1754DBQ is a pin-compatible alternative within the same package but offers different interface characteristics and performance metrics. Verify electrical compatibility before substitution.
