PCM1742KE

ADCs/DACs - Special Purpose Overview

The PCM1742KE 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, suitable for surface mount installation.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 192 kHz maximum sampling rate
• 106 dB signal-to-noise ratio and 0.007% THD+N
• Single 5V analog/digital power supply operation (4.5V–5.5V)
• SPI serial interface for configuration

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 against the manufacturer datasheet to confirm packaging type. The 'KE' designation typically indicates tube packaging, while other suffixes may denote reel quantities. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to ensure compatibility with assembly processes.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 5V single-supply architecture is required for high-performance audio conversion. Ensure the host controller supports the SPI interface protocol. Compare SNR and THD specifications against system requirements; this unit offers 106 dB SNR. Verify that the SSOP-16 footprint fits the PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM1742 series of audio DACs. It shares core electrical specifications with variants such as the PCM1742KEG4. The PCM1742KE serves as a standard commercial-grade option within the family, distinguished primarily by its packaging format compared to tape-and-reel alternatives.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1742KEG4 is a verified equivalent variant within the same product family. Both share identical electrical characteristics and pinouts. Selection between them depends solely on packaging preference (tube vs. reel) rather than functional differences.
