LTC2635HUD-HMI10#TRPBF

Overview

The LTC2635HUD-HMI10#TRPBF is a quad 10-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 a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It includes rail-to-rail output buffers and is guaranteed monotonic over the automotive temperature range of –40°C to 125°C. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. The part incorporates a power-on reset circuit configured to reset outputs to mid-scale in internal reference mode.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum Integral Nonlinearity (INL) error
• Integrated 4.096V precision reference with 10ppm/°C drift
• Automotive temperature grade (-40°C to 125°C)
• Power-on reset to mid-scale in internal reference mode

Applications

• Process control and industrial automation
• Portable equipment
• Automotive systems

Procurement Notes

Verify that the H suffix confirms the automotive temperature range and 4.5V minimum supply requirement. Confirm the MI suffix indicates the specific mid-scale power-on reset behavior for internal reference operation. Ensure the package matches the 16-lead QFN specification.

Selection Notes

Select this component when a 4.096V full-scale output is required with high linearity accuracy. The H-grade variant is necessary for environments exceeding 70°C. Verify that the 4.5V minimum supply voltage aligns with the system power rails, as lower voltages are not supported by this specific suffix configuration.

Part Context

This part belongs to the LTC2635 family of quad DACs. The HUD suffix denotes the 16-pin QFN package and automotive temperature grade. The H indicates the 4.096V full-scale internal reference, while MI specifies the mid-scale power-on reset function. Other variants include L-grade commercial parts and different reset configurations such as zero-scale or high-impedance states.

Replacement Considerations
