LTC2641CMS8-14#TRPBF

Overview

The LTC2641CMS8-14#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 supply current of 120µA. The device features a fast 1µs settling time and a low glitch impulse of 0.5nV·sec. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. The part is housed in an 8-lead MSOP package and is guaranteed monotonic over temperature.

Feature Summary

14-bit resolution with ±0.5 LSB INL/DNL accuracy
Low power consumption of 120µA typical supply current
Fast 1µs settling time to within 0.5LSB of full scale
Unbuffered voltage output directly drives loads >60kΩ

Applications

Process control and industrial automation
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the CMS8 designation corresponds to the 8-lead MSOP package type. Ensure the 'C' grade meets the required commercial operating temperature range of 0°C to 70°C for the specific application environment.

Selection Notes

Select this component when 14-bit precision is sufficient, offering lower cost than 16-bit variants while maintaining high linearity. The unbuffered output requires external buffering if driving low impedance loads below 60kΩ. Verify that the system interface supports the 3-wire synchronous protocol and that the 2V to VDD reference input range aligns with available reference voltages.

Part Context

This part belongs to the LTC2641 family of low-power DACs. The 'CMS8' indicates the 8-lead MSOP package, '14' specifies 14-bit resolution, and '#TRPBF' denotes tape and reel packaging with lead-free finish. It is distinct from the LTC2642, which supports bipolar operation via additional pins.
