LTC2641ACMS8-16#TRPBF

Overview

The LTC2641ACMS8-16#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 current consumption of 120µA. The device features an SPI/Microwire compatible 3-wire serial interface supporting clock rates up to 50MHz. Key electrical specifications include ±1LSB INL and DNL over temperature, a 1µs settling time, and a glitch impulse of 0.5nV·sec. It is housed in an 8-lead MSOP package and functions within the commercial temperature range of 0°C to 70°C.

Feature Summary

• 16-bit resolution with ±1LSB INL/DNL guaranteed over temperature
• Low power consumption of 120µA typical supply current
• Fast 1µs settling time to 16 bits
• Unbuffered voltage output directly drives loads >60kΩ

Applications

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

Procurement Notes

Verify that the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the AC grade meets the specific linearity requirements for the application. Ensure the MSOP-8 footprint matches the PCB design guidelines provided in the datasheet.

Selection Notes

Select this component when high accuracy (±1LSB) is required in a low-power environment. The unbuffered output requires careful consideration of load impedance to maintain linearity. For bipolar operation, the LTC2642 variant with internal scaling resistors is necessary instead of the LTC2641.

Part Context

This part belongs to the LTC2641 family of 16-/14-/12-bit VOUT DACs. The 'A' designation indicates enhanced performance specifications compared to standard grades. The 'MS8' denotes the 8-lead MSOP package, while '#TRPBF' specifies the tape and reel packaging format with lead-free finish.

Replacement Considerations

LTC2641ACMS8-16#PBF offers identical electrical characteristics but uses tube packaging instead of tape and reel.
