LTC2642IMS-12#PBF

Overview

The Analog Devices LTC2642IMS-12#PBF is a 12-bit unbuffered voltage output digital-to-analog converter (DAC) housed in a 10-lead MSOP package. It operates from 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 ±0.5 LSB integral nonlinearity (INL), ±0.5 LSB differential nonlinearity (DNL), and a settling time of 1µs to 0.5 LSB. It guarantees monotonic operation over the industrial temperature range of -40°C to +85°C.

Feature Summary

12-bit resolution with ±0.5 LSB INL and DNL errors
Unbuffered voltage output with low offset error of ±1 LSB
Industrial temperature range (-40°C to +85°C)
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 IMS-12 against the manufacturer's official documentation to confirm the 10-lead MSOP package and industrial temperature grade. Ensure compatibility with system requirements for unbuffered outputs and bipolar configuration capabilities if external amplification is utilized.

Selection Notes

Select this component for applications requiring high linearity (±0.5 LSB) in a compact surface-mount package. The unbuffered output architecture minimizes power consumption but requires careful consideration of load impedance, as loading affects gain error. Verify that the system can accommodate the midscale power-on reset state inherent to the LTC2642 family.

Part Context

This part belongs to the LTC2642 family of 16-/14-/12-bit VOUT DACs. Unlike the LTC2641, the LTC2642 includes internal matched scaling resistors (RFB and INV) designed for use with an external precision operational amplifier to generate a bipolar output swing ranging from -VREF to +VREF.
