PCM1742KE/2KG4

ADCs/DACs - Special Purpose Overview

The PCM1742KE/2KG4 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 delta-sigma modulation. The device operates on a single power supply ranging from 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 106 dB and a total harmonic distortion plus noise of 0.007%. It utilizes an SPI interface for control and is housed in a 16-pin SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm RoHS compliance status and exact pinout compatibility, as suffixes may indicate packaging or environmental variations distinct from the base PCM1742KE model.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 5V single-supply architecture is required alongside high dynamic range specifications. Ensure the design accommodates the SSOP-16 footprint and that the host microcontroller supports the necessary SPI communication protocol for register configuration.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1742 series of audio DACs. It shares core electrical characteristics with variants such as the PCM1742KE and PCM1742KEG4, differing primarily in reel packaging quantities or specific manufacturing lot identifiers rather than functional circuitry.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1742KE and PCM1742KEG4 are functionally equivalent alternatives within the same family. Verify package availability and specific ordering suffix requirements before substitution.
