LTC2636IMS-HMX10#TRPBF

Overview

The LTC2636IMS-HMX10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Packaged in a 16-lead MSOP, it includes hardware clear (CLR) and asynchronous DAC update (LDAC) pins. The part guarantees monotonicity over the automotive temperature range of –40°C to 125°C and incorporates a power-on reset circuit that sets outputs to mid-scale.

Feature Summary

• Octal architecture with eight independent 10-bit DAC channels
• Integrated 10ppm/°C reference yielding 4.096V full-scale output
• Automotive grade performance guaranteed from –40°C to 125°C
• SPI/MICROWIRE interface supporting 50MHz clock speeds

Applications

• Process control and industrial automation systems
• Automatic test equipment requiring multi-channel precision
• Portable battery-powered instrumentation
• Optical networking signal generation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the IMS designation corresponds to the 16-lead MSOP package and H-grade automotive temperature rating. Ensure the MX10 code matches the required external reference mode power-on reset behavior for system initialization requirements.

Selection Notes

Select this component when eight synchronized analog outputs are required with high linearity and low drift. The H-grade variant is necessary for environments exceeding 85°C. Choose the MX suffix if the application demands mid-scale initialization during external reference operation rather than zero-scale or internal reference mid-scale states.

Part Context

This part belongs to the LTC2636 family of octal DACs, which also offers 12-bit and 8-bit resolutions. Variants include the LTC2636-L series for 2.5V full-scale applications operating down to 2.7V. The IMS package distinguishes it from the DE DFN package options, providing different thermal and pin-out characteristics for surface-mount assembly.
