LTC2641IMS8-16#PBF

Overview

The Analog Devices LTC2641IMS8-16#PBF is a 16-bit unbuffered voltage output digital-to-analog converter (DAC) housed in an 8-lead MSOP package. It operates from a single 2.7V to 5.5V supply with a typical current consumption of 120µA. The device features a maximum integral nonlinearity (INL) error of ±1LSB and differential nonlinearity (DNL) of ±1LSB over temperature, ensuring monotonic operation. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. A power-on reset circuit clears the DAC output to zero scale upon initial power application.

Feature Summary

16-bit resolution with ±1LSB INL/DNL guaranteed over temperature
Unbuffered voltage output with low offset error of ±1LSB
Fast 1µs settling time to 16 bits
Low glitch impulse of 0.5nV•sec

Applications

Process control and industrial automation
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the specific ordering suffix IMS8 corresponds to the 8-lead MSOP package and I-grade temperature range (-40°C to 85°C). Confirm RoHS compliance status via manufacturer documentation before integration. Ensure the external reference voltage remains within the 2V to VDD range for proper operation.

Selection Notes

Select this component when high DC accuracy and low power consumption are required in a small footprint. The unbuffered output requires loads greater than 60kΩ to maintain linearity specifications. For bipolar output requirements, consider the LTC2642 family instead, as the LTC2641 provides only unipolar output.

Part Context

This part belongs to the LTC2641/LTC2642 family of 16-/14-/12-bit VOUT DACs. The IMS8 suffix denotes the 8-lead MSOP package variant. Other package options include the 3mm x 3mm DFN (DD) and obsolete SO (S8) packages. The 'I' grade indicates an extended industrial temperature range compared to the commercial 'C' grade.
