LTC2636CMS-HMI8#TRPBF

Overview

The LTC2636CMS-HMI8#TRPBF is an octal, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 10ppm/°C integrated reference with a full-scale output of 2.5V and operates on a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers guaranteed monotonic over the temperature range. It communicates via a 3-wire SPI/MICROWIRE interface with clock rates up to 50MHz. This specific part number indicates a commercial temperature grade (0°C to 70°C), MSOP-16 package, and power-on reset to mid-scale in internal reference mode.

Feature Summary

• Octal architecture with 8 independent 8-bit DAC channels
• Integrated 10ppm/°C reference providing 2.5V full-scale output
• Rail-to-rail output buffers with ultralow crosstalk (<2.4nV•s)
• Power-on reset to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify the ordering suffix #TRPBF confirms tape and reel packaging and lead-free status. Confirm the 'MS' designation matches the required 16-lead MSOP package for the design. Ensure the 'C' grade meets the 0°C to 70°C operating temperature requirements of the application environment.

Selection Notes

Select this part when eight low-cost, 8-bit voltage outputs are needed with a fixed 2.5V span. The H-grade variant (-HMI8) is required if operation above 70°C or down to -40°C is necessary. Choose the MX suffix if mid-scale reset is required during external reference operation instead of internal.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. Variants differ by resolution, package type (DFN or MSOP), temperature grade (C, I, or H), and power-on reset behavior (Zero-Scale, Mid-Scale Internal, or Mid-Scale External).

Replacement Considerations

Public confirmed substitute part numbers: None.
