LTC2637CMS-HZ10#TRPBF

Overview

The LTC2637CMS-HZ10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It features a high-accuracy internal reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 2.5V. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches and a power-on reset circuit configured to reset outputs to zero-scale in internal reference mode. The component is housed in a 14-lead DFN package.

Feature Summary

• Octal 10-bit resolution with rail-to-rail output buffers guaranteed monotonic over the operating temperature range
• Integrated precision reference yielding a 2.5V full-scale output with ±10ppm/°C drift
• Power-on reset function defaults outputs to zero-scale when using the internal reference
• Ultralow DAC-to-DAC crosstalk specification of less than 3nV•s

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics
• Optical networking infrastructure

Procurement Notes

Verify that the specific suffix #TRPBF corresponds to the tape and reel packaging configuration containing 2500 pieces as defined in the manufacturer's ordering guide. Confirm the C-grade commercial temperature rating (0°C to 70°C) aligns with the thermal requirements of the target application environment before finalizing procurement.

Selection Notes

Select this part for applications requiring multiple low-power voltage outputs controlled via I2C. Ensure the system supply voltage remains within the 2.7V to 5.5V range compatible with the LTC2637-L series. Consider the H-grade variant if the application requires a higher 4.096V full-scale output or extended automotive temperature ranges up to 125°C.

Part Context

This component belongs to the LTC2637 family of octal DACs, which also includes 8-bit and 12-bit resolution variants. The 'L' designation indicates the 2.5V internal reference version, while 'H' denotes the 4.096V version. The 'MS' suffix identifies the 16-lead MSOP package, whereas 'DE' identifies the 14-lead DFN package used by this specific model.

Replacement Considerations

Direct functional equivalents within the same family include the LTC2637CDE-HZ10#TRPBF for different package options or the LTC2637IMS-HZ10#TRPBF for industrial temperature grades. Verify pin compatibility and I2C addressing configurations when substituting between package types or temperature grades.
