LTC2754IUKG-12

Digital To Analog Converters Overview

The LTC2754IUKG-12#PBF is a quad-channel, 12-bit digital-to-analog converter (DAC) from Analog Devices. It features SoftSpan technology, allowing output ranges to be adjusted via external resistors. The device operates with a single supply voltage and includes an internal reference. Key electrical parameters include a settling time of 2 µs, differential nonlinearity (DNL) of 1 LSB, integral nonlinearity (INL) of 1 LSB, and gain error of 0.5 LSB. It consumes 500 nA of operating current with power dissipation of 1.5 µW. The component supports 3-Wire or SPI interfaces and functions within a temperature range of -40°C to +85°C in a 52-pin QFN package.

Digital To Analog Converters Procurement Notes

Verify the suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the I suffix denotes industrial temperature range operation (-40°C to +85°C). Ensure the UKG package code matches the required 52-pin QFN footprint for PCB layout compatibility. Check datasheet for specific resistor values needed to configure the SoftSpan output ranges.

Digital To Analog Converters Selection Notes

Select this model when four independent 12-bit current-output DACs are required in a compact form factor. The SoftSpan feature allows customization of output swing without changing hardware. Verify that the external reference voltage requirement aligns with system constraints, as the device supports external references up to 15V. Consider the 2 µs settling time for bandwidth requirements.

Digital To Analog Converters Part Context

This part belongs to the LTC2754 family of SoftSpan DACs. The '12' suffix specifies 12-bit resolution. Other variants may offer different resolutions or channel counts. The IUKG package is a 52-lead Thin Profile QFN designed for surface-mount assembly. This specific part number integrates the industrial temperature grade and Pb-free compliance.

Digital To Analog Converters Replacement Considerations

Direct replacements must match the quad-channel architecture, 12-bit resolution, and 52-QFN package. Verify pinout compatibility if substituting with other Analog Devices DACs. Ensure the replacement supports SoftSpan functionality if adjustable output ranges are critical to the design.
