LTC2641CMS8-16#TRPBF

Overview

The LTC2641CMS8-16#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 supply current of 120µA. The device features a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1LSB, a glitch impulse of 0.5nV·sec, and a settling time of 1µs to 16 bits. It is housed in an 8-lead MSOP package and guarantees monotonic operation over temperature.

Feature Summary

• 16-bit resolution with ±1LSB INL and ±1LSB DNL performance
• Low power consumption of 120µA typical supply current
• Fast 1µs settling time to 16-bit accuracy
• Unbuffered voltage output directly drives loads greater than 60kΩ

Applications

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

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the CMS8 designation corresponds to the 8-lead MSOP package. Ensure the specific temperature grade matches the design requirements for commercial or industrial ranges.

Selection Notes

Select this component for applications requiring high linearity and low power in a small footprint. The unbuffered output requires careful consideration of load impedance to maintain specified linearity errors. Verify that the system can accommodate the 6.2kΩ output resistance for gain error calculations.

Part Context

This part belongs to the LTC2641 family of 16-/14-/12-bit DACs. The 'CMS8' suffix identifies the 8-lead MSOP package variant. The '#TRPBF' suffix denotes lead-free finish and tape and reel shipping configuration. It is distinct from the LTC2642, which supports bipolar output configurations.
