LTC2635CUD-HMI12#TRPBF

Overview

The LTC2635CUD-HMI12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. 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, double-buffered data latches, and guarantees monotonicity 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.

Feature Summary

Quad 12-bit resolution with maximum INL error of ±2.5 LSB
Integrated 4.096V full-scale reference with 10ppm/°C drift
Power-on reset configured to mid-scale in internal reference mode
Ultralow crosstalk between DACs at 3nV•s

Applications

Process control and industrial automation
Power supply margining
Automotive systems

Procurement Notes

Verify the package type corresponds to the 16-pin QFN format indicated by the 'UD' suffix in the part number. Confirm that the power-on reset behavior matches the 'MI' configuration for mid-scale initialization. Ensure the operating environment stays within the specified 4.5V to 5.5V supply range required for the H-grade variant.

Selection Notes

Select this component when a quad-channel DAC with high accuracy and low noise is required. The H-grade designation ensures operation up to 125°C, suitable for automotive applications. The MI suffix specifies the initial state upon power-up. Consider external reference options if a different full-scale voltage is needed, though this part is optimized for the internal 4.096V setting.

Part Context

This part belongs to the LTC2635 family, which includes 8-bit, 10-bit, and 12-bit variants. The 'H' indicates the automotive temperature grade and 4.096V full-scale output, while 'L' denotes the commercial grade with 2.5V output. The 'UD' specifies the 16-lead QFN package, distinct from the 10-lead MSOP option.
