LTC2754BCUKG-16#TRPBF

Overview

The LTC2754BCUKG-16#TRPBF is a quad 16-bit multiplying serial-input current-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7V to 5.5V supply and guarantees monotonicity over temperature. The device features SoftSpan technology, allowing six output ranges (0V to 5V, 0V to 10V, ±2.5V, ±5V, ±10V, -2.5V to 7.5V) to be programmed via a 3-wire SPI interface or pin-strapped. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 2μs, and a low supply current of 1μA. It includes voltage-controlled offset and gain adjustments, serial readback capabilities, and power-on reset functionality.

Feature Summary

• Quad 16-bit resolution with guaranteed monotonic operation over temperature
• SoftSpan architecture supporting six software-programmable or pin-strapped output ranges up to ±10V
• Low glitch impulse of 1.25nV•s at 5V supply and 0.26nV•s at 3V supply
• Serial readback of all on-chip registers and voltage-controlled offset/gain trim pins

Applications

• High resolution offset and gain adjustment circuits
• Process control and industrial automation systems
• Automatic test equipment
• Data acquisition systems

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the BC grade corresponds to the commercial temperature range (0°C to 70°C) as specified in the ordering information table. Ensure the external reference voltage and supply conditions match the datasheet specifications for optimal performance.

Selection Notes

Select this component when four independent 16-bit current-output DACs are required in a compact QFN package. The BC grade is suitable for commercial applications requiring 0°C to 70°C operation. Consider the IOUT configuration if external operational amplifiers are needed for voltage conversion, noting the internal feedback resistors are 810kΩ.

Part Context

This part belongs to the LTC2754 family of SoftSpan DACs. The 'B' designation identifies the BC grade variant with a commercial temperature range. The '16' indicates 16-bit resolution. The '#TRPBF' suffix denotes Tape & Reel packaging with lead-free finish. Other variants include the BI grade for industrial temperatures and AC/AI grades for higher precision.

Replacement Considerations

Direct replacements within the same package and specification include LTC2754ACUKG-16#TRPBF for improved linearity specs, or LTC2754BIUKG-16#TRPBF for extended industrial temperature range (-40°C to 85°C). Verify that the replacement's INL/DNL specifications meet the application requirements.
