LTC2641AIDD-16#TRPBF

Overview

The LTC2641AIDD-16#TRPBF is a 16-bit unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7V to 5.5V supply with a typical current consumption of 120µA. The device features a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include ±1LSB INL and DNL over temperature, a settling time of 1µs to 16 bits, and a glitch impulse of 0.5nV·sec. It is housed in an 8-lead 3mm × 3mm DFN package and supports an industrial operating temperature range of –40°C to +85°C.

Feature Summary

16-bit resolution with ±1LSB INL/DNL guaranteed over temperature
Low power consumption of 120µA typical supply current
Fast 1µs settling time for 16-bit accuracy
Unbuffered voltage output directly drives loads >60kΩ

Applications

Process control and industrial automation systems
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the 'A' grade designation ensures ±1LSB linearity performance across the full industrial temperature range. Ensure the DFN package exposed pad is soldered to PCB ground for proper thermal and electrical operation.

Selection Notes

Select this part for applications requiring high precision unipolar voltage generation with minimal power usage. The unbuffered output requires load resistance greater than 60kΩ to maintain specified linearity. For bipolar output requirements, consider the LTC2642 family instead. Verify reference voltage input range compatibility between 2V and VDD.

Part Context

This component belongs to the LTC2641/LTC2642 family of low-power DACs. The 'A' suffix denotes improved linearity specifications compared to standard grades. The 'I' suffix indicates the industrial temperature range (-40°C to 85°C). The 'DD' code specifies the 8-lead 3mm x 3mm DFN package.
