LTC2641IDD-14#PBF

Overview

The LTC2641IDD-14#PBF is a 14-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) and differential nonlinearity (DNL) of ±0.5 LSB, a settling time of 1µs to 0.5 LSB, and a glitch impulse of 0.5 nV·sec. It is housed in an 8-lead 3mm × 3mm DFN package and is guaranteed monotonic over the industrial temperature range of -40°C to +85°C.

Feature Summary

14-bit resolution with ±0.5 LSB INL and DNL errors
Unbuffered voltage output driving loads >60kΩ without degrading linearity
50MHz SPI/QSPI/Microwire compatible serial interface
Power-on reset clears DAC output to zero scale

Applications

Process control and industrial automation
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the IDD suffix corresponds to the industrial temperature grade (-40°C to +85°C). Ensure the 14-bit variant matches system resolution requirements compared to 12-bit or 16-bit options within the same family.

Selection Notes

Select this component for applications requiring low power consumption and high accuracy in a compact footprint. The unbuffered output requires careful consideration of load impedance; loads below 60kΩ will increase gain error. For bipolar operation, the LTC2642 series is required instead of the LTC2641.

Part Context

This part belongs to the LTC2641/LTC2642 family of SoftSpan DACs. The LTC2641 provides unipolar output, while the LTC2642 includes internal scaling resistors for bipolar configurations. The 'IDD' designation specifies the industrial temperature range and DFN package, distinguishing it from commercial grades or MSOP packages.
