Overview
The LTC2642CMS-12#PBF is a 12-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 ±0.5 LSB integral nonlinearity (INL), ±0.5 LSB differential nonlinearity (DNL), and a settling time of 1µs to 0.5 LSB. It includes matched scaling resistors for bipolar operation with an external op amp, asynchronous clear functionality, and power-on reset to midscale.
Feature Summary
- 12-bit resolution with ±0.5 LSB INL/DNL and 1µs settling time
- Unbuffered voltage output with low 120µA supply current
- Integrated matched scaling resistors for bipolar output generation
- 50MHz SPI/Microwire compatible serial interface
Applications
- Process control and industrial automation systems
- Automatic test equipment
- Data acquisition systems
Procurement Notes
Verify the package type matches the design requirements, as this specific part number corresponds to the 10-lead MSOP package. Confirm that the commercial temperature range (0°C to 70°C) aligns with the application environment. Ensure the system design accounts for the unbuffered output impedance when driving loads to maintain specified linearity performance.
Selection Notes
Select this component for applications requiring high accuracy in a small footprint without the need for internal buffering. The integrated bipolar resistors simplify designs requiring dual-polarity outputs using a single supply. Consider the 6.2kΩ output resistance when calculating gain errors caused by external loading conditions.
Part Context
This part belongs to the LTC2642 family of 16-, 14-, and 12-bit DACs. The 'CMS' suffix indicates the 10-lead MSOP package, while the '-12' denotes 12-bit resolution. The '#PBF' suffix signifies a lead-free finish. It shares the same core architecture and interface as other variants but differs in pin count due to the inclusion of bipolar scaling resistor pins.
Replacement Considerations
Direct replacements within the same package and resolution include other LTC2642CMS-12 variants with different temperature grades, such as the LTC2642AIMS-12#PBF for extended industrial temperature ranges.
