LTC2754AIUKG-16#TRPBF

Overview

The LTC2754AIUKG-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 the -40°C to +85°C temperature range. The device features SoftSpan technology, allowing six output ranges (up to ±10V) to be programmed via a 3-wire SPI interface or pin-strapped. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 2μs for 16-bit accuracy, and a low glitch impulse of 1.25nV•s at 5V. It incorporates voltage-controlled offset and gain adjustments, serial readback capabilities, and power-on reset functions.

Feature Summary

• Quad 16-bit resolution with guaranteed monotonic operation over temperature
• SoftSpan architecture supporting six programmable output ranges: 0V to 5V, 0V to 10V, ±2.5V, ±5V, ±10V, and -2.5V to +7.5V
• Maximum INL error of ±1 LSB and differential nonlinearity (DNL) of ±0.2 LSB
• Voltage-controlled offset and gain trim pins for precision calibration

Applications

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

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format as specified in the manufacturer's order information table. Confirm the temperature grade 'I' indicates an operating range of –40°C to +85°C. Ensure the component matches the 52-lead QFN package dimensions and lead-free finish requirements defined in the datasheet.

Selection Notes

Select this model when 16-bit linearity with ±1 LSB INL is required across the full industrial temperature range. The AI grade offers tighter static performance compared to standard variants. Consider the 52-pin QFN package size and the need for external reference inverting amplifiers if bipolar ranges are utilized. Verify that the 2μs settling time meets the system speed requirements.

Part Context

This part belongs to the LTC2754 family of SoftSpan DACs. The 'A' suffix denotes the highest performance grade within the 16-bit variant, ensuring ±1 LSB INL without adjustments. The 'I' suffix specifies the industrial temperature range. The '#TRPBF' suffix indicates the specific tape and reel packaging configuration for automated assembly.

Replacement Considerations

The LTC2754BIUKG-16#TRPBF is a confirmed alternative within the same family, offering 16-bit resolution but with a wider maximum INL of ±2 LSB. Other family members like the LTC2754CUKG-16 provide lower performance grades. No direct cross-family replacements are documented in the provided source material.
