LTC2642IMS-16#TRPBF

Overview

The LTC2642IMS-16#TRPBF is a 16-bit unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead MSOP package. It operates on a single supply of 2.7V to 5.5V 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) of ±1 LSB and differential nonlinearity (DNL) of ±1 LSB over temperature. It includes matched scaling resistors for bipolar operation with an external op amp, asynchronous clear functionality, and power-on reset to midscale.

Feature Summary

16-bit resolution with guaranteed monotonicity over temperature
Unbuffered voltage output with low offset error of ±1 LSB
Integrated bipolar scaling resistors for external amplifier configuration
50MHz SPI/QSPI/MICROWIRE compatible serial interface

Applications

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

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the IMS designation corresponds to the 10-lead MSOP package variant. Ensure the I grade meets the required -40°C to +85°C operating temperature range for the specific application environment.

Selection Notes

Select this component when bipolar output swing is required using an external precision op amp, leveraging the internal matched RFB/INV resistors. Choose the 16-bit version for applications demanding ±1 LSB INL/DNL accuracy. Ensure the load impedance exceeds 60kΩ to maintain linearity specifications due to the unbuffered output architecture.

Part Context

This part belongs to the LTC2641/LTC2642 family of 16-/14-/12-bit VOUT DACs. The LTC2642 variant specifically distinguishes itself from the LTC2641 by including internal bipolar scaling resistors and powering up to midscale via its CLR pin, whereas the LTC2641 powers up to zero scale.
