LTC2642CDD-14#PBF

Overview

The LTC2642CDD-14#PBF is a single-channel, 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 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 settling time of 1µs to ±0.5LSB, an integral nonlinearity (INL) of ±0.5LSB, and a differential nonlinearity (DNL) of ±0.5LSB. It is housed in a 10-lead 3mm × 3mm DFN package and is guaranteed monotonic over temperature.

Feature Summary

14-bit resolution with ±0.5LSB INL and DNL guarantees
Unbuffered voltage output with low 120µA supply current
50MHz SPI/MICROWIRE compatible 3-wire serial interface
Power-on reset clears DAC output to midscale

Applications

Process control and industrial automation
Automatic test equipment
Data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and temperature range. Ensure that the external reference voltage applied to the REF pin remains within the specified 2V to VDD range for proper operation. Confirm compatibility with the system's serial interface timing requirements before integration.

Selection Notes

Select this component when bipolar output capability is required alongside high precision. Unlike the LTC2641, the LTC2642 includes internal matched scaling resistors for use with an external op amp to generate a bipolar output swing. Ensure the application can accommodate the unbuffered output impedance of approximately 6.2kΩ or provides appropriate loading.

Part Context

This part belongs to the LTC2641/LTC2642 family of 16-, 14-, and 12-bit voltage output DACs. The 'C' suffix indicates a commercial operating temperature range of 0°C to 70°C. The 'DD' suffix denotes the 10-lead 3mm × 3mm plastic DFN package. The '#PBF' suffix indicates a lead-free finish compliant with RoHS standards.
