LTC2641IDD-16#TRPBF

Overview

The LTC2641IDD-16#TRPBF is a 16-bit unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices, packaged in an 8-lead 3mm × 3mm DFN. It operates on a single supply of 2.7V to 5.5V with a typical supply current of 120µA. The device features a maximum integral nonlinearity (INL) error of ±1LSB and differential nonlinearity (DNL) of ±1LSB over the industrial temperature range (-40°C to +85°C). It utilizes a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. Key functional attributes include a power-on reset that clears the DAC output to zero scale and an asynchronous clear pin.

Feature Summary

16-bit resolution with guaranteed monotonic operation over temperature
Unbuffered voltage output with low offset error of ±1LSB
Fast 1µs settling time to 16 bits with 0.5nV•sec glitch impulse
Industrial temperature range (-40°C to +85°C) in 8-lead DFN package

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 IDD suffix corresponds to the -40°C to +85°C industrial operating temperature range. Ensure the specific lot date code meets project requirements as manufacturing dates vary by batch.

Selection Notes

Select this component for applications requiring high precision unipolar voltage generation without internal buffering. The unbuffered output requires external loading considerations; loads greater than 60kΩ maintain linearity specifications. For bipolar output requirements, consider the LTC2642 family instead. Verify reference voltage stability as it directly determines full-scale output accuracy.

Part Context

This part belongs to the LTC2641/LTC2642 family of 16-/14-/12-bit VOUT DACs. The LTC2641 variant provides unipolar output, while the LTC2642 supports bipolar configurations via internal scaling resistors. The IDD-16 designation specifies the 16-bit resolution and industrial temperature grade within the 3mm × 3mm DFN form factor.
