LTC2636IMS-HMI12#TRPBF

Overview

The LTC2636IMS-HMI12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C temperature range, and communicates via a 3-wire SPI/MICROWIRE interface supporting clock rates up to 50MHz. It incorporates double-buffered data latches, power-on reset to mid-scale in internal reference mode, and low noise characteristics.

Feature Summary

• Octal 12-Bit Resolution with ±2.5 LSB Maximum INL Error
• Integrated 4.096V Precision Reference (10ppm/°C Drift)
• Rail-to-Rail Output Buffers with Ultralow Crosstalk (<2.4nV•s)
• Power-On Reset to Mid-Scale in Internal Reference Mode

Applications

• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific suffix #TRPBF indicates a tape and reel packaging configuration containing 2500 pieces. Confirm the IMS designation corresponds to the 16-lead MSOP package and H-grade automotive temperature rating (-40°C to 125°C). Ensure compatibility with the required 4.5V to 5.5V supply voltage for the H-series variant.

Selection Notes

Select this part for applications requiring eight independent 12-bit channels with high accuracy and wide operating temperature ranges. The HMI12 suffix specifies the 4.096V full-scale range, mid-scale power-on reset behavior, and 12-bit resolution. Consider the MSOP package thermal resistance limits when determining maximum output current capabilities under continuous operation.

Part Context

This component belongs to the LTC2636 family of octal DACs, which also offers 10-bit and 8-bit resolutions, as well as L-grade commercial variants with 2.5V full-scale outputs. The H-grade designation distinguishes it by its extended temperature range and higher supply voltage requirements compared to the standard C or I grades.

Replacement Considerations

Direct replacements within the same family include LTC2636IMS-LMI12#TRPBF for 2.5V full-scale applications or LTC2636IMS-HMX12#TRPBF if external reference operation with mid-scale reset is preferred. Verify pinout compatibility and thermal performance when substituting.
