LTC2642CMS-14#TRPBF

Overview

The LTC2642CMS-14#TRPBF is a 14-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 ±0.5 LSB integral nonlinearity (INL), ±0.5 LSB differential nonlinearity (DNL), and a settling time of 1µs to 0.5 LSB. The part is housed in a 10-lead MSOP package and includes internal matched scaling resistors for bipolar operation.

Feature Summary

14-bit resolution with guaranteed monotonicity over temperature
Low power consumption of 120µA typical supply current
Fast 1µs settling time to 0.5 LSB accuracy
Internal matched scaling resistors enable bipolar output configuration

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube packaging. Confirm the 'CMS' designation corresponds to the 10-lead MSOP package variant. Ensure the component meets RoHS compliance requirements for the intended manufacturing process.

Selection Notes

Select this model when bipolar output capability is required, as it includes internal scaling resistors unlike the LTC2641. Choose the 14-bit version if system precision requirements are met by ±0.5 LSB INL/DNL, offering lower power than the 16-bit variants. Verify that the load impedance exceeds 60kΩ to maintain linearity specifications in unbuffered mode.

Part Context

This component belongs to the LTC2641/LTC2642 family of low-power DACs. The LTC2642 variant is distinguished by its bipolar architecture support via internal resistors. The CMS-14 suffix indicates a 14-bit resolution device packaged in a 10-lead MSOP format, suitable for space-constrained designs requiring moderate precision.
