PCM1780DBQR

ADCs/DACs - Special Purpose Overview

The PCM1780DBQR 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 architecture. The device operates on a single power supply ranging from 4.5 V to 5.5 V and includes two DAC outputs. It utilizes an SPI interface for control and data input. The component is housed in a 16-pin SSOP package and is rated for operation within a temperature range of -20°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 192 kHz maximum sampling rate
• Enhanced multilevel delta-sigma modulation technology
• Single-supply operation (4.5 V to 5.5 V)
• SPI serial interface compatibility

ADCs/DACs - Special Purpose Applications

• High-fidelity audio systems
• Professional audio equipment
• Home theater receivers

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DBQR' indicates the reel packaging variant when sourcing. Confirm that the SSOP-16 package dimensions match the target PCB footprint. Ensure the voltage supply aligns with the 4.5 V to 5.5 V operational range specified in the datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-resolution stereo audio conversion with a compact surface-mount footprint. Compare against the PCM1782 if I2S interface support is required instead of SPI. Verify thermal requirements against the -20°C to +85°C operating range.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1780 series, which includes variants like the PCM1780DBQ. The DBQR designation specifically denotes the tape-and-reel packaging format, distinguishing it from tube-packaged equivalents while maintaining identical electrical characteristics.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1782DBQR is a functional alternative within the same family but uses an I2S interface rather than SPI. Direct pin-for-pin replacement requires verifying interface compatibility.
