LTC2754IUKG-12#TRPBF

Digital To Analog Converters Overview

The LTC2754IUKG-12#TRPBF is a quad 12-bit multiplying serial-input, current-output digital-to-analog converter from Analog Devices. It operates on a single 2.7V to 5.5V supply and features SoftSpan technology for six selectable output ranges: 0V to 5V, 0V to 10V, -2.5V to 7.5V, ±2.5V, ±5V, and ±10V. The device guarantees monotonicity over temperature with a maximum INL error of ±1 LSB. Key electrical parameters include a 2μs settling time, low glitch impulse of 1.25nV•s at 5V, and a maximum supply current of 1μA. It utilizes a 3-wire SPI interface with readback capabilities.

Digital To Analog Converters Feature Summary

• Quad 12-bit resolution with guaranteed monotonic operation over the full operating temperature range (-40°C to 85°C).
• SoftSpan architecture allows software-programmable selection among six output voltage ranges up to ±10V.
• Voltage-controlled offset and gain trim pins (VOSADJX, GEADJX) enable precision calibration.
• Integrated power-on reset and CLR pin ensure DAC outputs return to 0V upon initialization.

Digital To Analog Converters Applications

• Process control and industrial automation systems requiring high-resolution analog outputs.
• Automatic test equipment needing precise current or voltage generation.
• Data acquisition systems utilizing multiplying DAC functionality.

Digital To Analog Converters Procurement Notes

Verify that the specific part number corresponds to the 12-bit variant with the 'I' grade for industrial temperature range (-40°C to 85°C). Confirm the '#TRPBF' suffix indicates tape and reel packaging suitable for automated assembly. Ensure the design supports the 52-pin QFN footprint and exposed pad grounding requirements specified in the datasheet.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit channels are required within a single package. The SoftSpan feature is critical if dynamic range switching between unipolar and bipolar spans is needed without hardware changes. Consider the 2μs settling time and 1.25nV•s glitch impulse for applications demanding fast transient response and low noise.

Digital To Analog Converters Part Context

This part belongs to the LTC2754 family of SoftSpan DACs. The 'I' designation specifies the industrial temperature grade, while the '12' indicates 12-bit resolution. Higher performance variants exist, such as the LTC2754A-16, which offers tighter linearity specifications (±0.4 LSB INL) but may have different cost and availability profiles.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the LTC2754CUKG-12#TRPBF for commercial temperature range (0°C to 70°C) or the LTC2754BCUKG-16#TRPBF for 16-bit resolution. Verify that any substitute maintains the 52-lead QFN package dimensions and pinout compatibility.
