LTC2642CMS-16#TRPBF

Overview

The LTC2642CMS-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 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 and differential nonlinearity (DNL) of ±1LSB over temperature. The DAC settles to 16-bit accuracy within 1µs and includes a power-on reset circuit that initializes the output to midscale. It is housed in a 10-lead MSOP package.

Feature Summary

16-bit resolution with guaranteed monotonic operation over temperature
Unbuffered voltage output capable of driving loads greater than 60kΩ
Integrated bipolar scaling resistors for external op amp configuration
Power-on reset clears DAC output to midscale upon initial power application

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 when sourcing components. Confirm the manufacturer is Analog Devices Inc. or its authorized subsidiary, Linear Technology. Ensure the part number matches the 16-bit resolution variant within the LTC2642 family.

Selection Notes

Select this component for applications requiring high precision unipolar or bipolar voltage generation. The LTC2642 variant is necessary if bipolar output swing using an external amplifier is required, unlike the LTC2641. Ensure the load impedance exceeds 60kΩ to maintain specified linearity errors without buffering.

Part Context

This part belongs to the LTC2641/LTC2642 family of low-power DACs. The CMS8 suffix indicates a plastic MSOP package, while the -16 denotes 16-bit resolution. The #TRPBF suffix specifies tape and reel packaging with lead-free finish. The 'C' grade indicates a commercial operating temperature range of 0°C to 70°C.
