LTC2637HMS-HMI12#TRPBF

Overview

The LTC2637HMS-HMI12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a high-accuracy internal reference with a 4.096V full-scale output and a temperature coefficient of 10ppm/°C. The device operates on a single 4.5V to 5.5V supply and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches, rail-to-rail output buffers, and a power-on reset circuit configured to reset to mid-scale in internal reference mode. The component is housed in a 16-lead MSOP package.

Feature Summary

Octal architecture providing eight independent 12-bit DAC channels
Integrated precision reference yielding 4.096V full-scale output with ±10ppm/°C drift
Ultralow DAC-to-DAC crosstalk specified at 3nV•s typical value
Power-on reset function set to mid-scale for internal reference operation

Applications

Mobile communications systems
Process control and industrial automation
Automatic test equipment
Portable equipment
Automotive applications
Optical networking

Procurement Notes

Verify the H-grade automotive temperature rating (-40°C to 125°C) and the specific HMI12 configuration which dictates the 4.096V internal reference and mid-scale power-on reset behavior. Confirm the MSOP-16 package type matches the design footprint requirements.

Selection Notes

Select this part when eight synchronized voltage outputs are required with high linearity and low crosstalk. Ensure the system supply voltage remains within the 4.5V to 5.5V range mandated by the H-grade internal reference. Verify that the I2C address pins (CA0, CA1, CA2) can be configured to avoid bus conflicts.

Part Context

This component belongs to the LTC2637 family of octal DACs available in DFN and MSOP packages. Variants differ by resolution (8, 10, or 12 bits), internal reference voltage (2.5V or 4.096V), and power-on reset behavior. The H suffix denotes the extended temperature grade suitable for automotive environments.
