LTC2642IMS-12#TRPBF

Overview

The LTC2642IMS-12#TRPBF is a 12-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. It includes an asynchronous clear pin and power-on reset functionality that sets the output to midscale upon initialization. The component is housed in a 10-lead MSOP package and is guaranteed monotonic over temperature.

Feature Summary

12-bit resolution with ±0.5 LSB INL and DNL errors
Unbuffered voltage output driving loads >60kΩ
Bipolar operation capability via internal scaling resistors
Power-on reset clears DAC output to midscale

Applications

Process control and industrial automation
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging when sourcing this specific part number. Confirm the IMS designation corresponds to the 10-lead MSOP package variant. Ensure the supplier provides documentation confirming the -40°C to +85°C industrial temperature range associated with the 'I' grade.

Selection Notes

Select this model for applications requiring bipolar output swings using an external op-amp, as the LTC2642 includes matched RFB and INV pins for this purpose. Choose the 12-bit version if lower resolution is sufficient to minimize power consumption while maintaining high speed. Verify that the load impedance exceeds 60kΩ to maintain specified linearity without buffering.

Part Context

This component belongs to the LTC2641/LTC2642 family of low-power, high-resolution DACs. The LTC2642 variant specifically supports bipolar configurations through its additional INV and RFB pins, distinguishing it from the unipolar-only LTC2641. The IMS suffix denotes the MSOP package, while the TRPBF suffix specifies tape and reel delivery.
