LTC2634HUD-LZ12#TRPBF

Overview

The LTC2634HUD-LZ12#TRPBF is a quad 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 utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. It includes rail-to-rail output buffers, double-buffered data latches, and power-on reset to zero-scale. Packaged in a 16-lead QFN, it is AEC-Q100 qualified for automotive applications.

Feature Summary

Quad 12-bit resolution with ±2.5 LSB maximum INL error
Integrated 4.096V precision reference with 10ppm/°C drift
AEC-Q100 qualified for automotive temperature range (-40°C to 125°C)
Ultralow DAC-to-DAC crosstalk of 2.4nV•s

Applications

Automotive systems
Process control and industrial automation
Portable equipment

Procurement Notes

Verify the #TRPBF suffix indicates a tape and reel packaging format containing 2,500 units. Confirm the H-grade designation corresponds to the specified automotive operating temperature range of -40°C to 125°C. Ensure the LZ12 configuration matches the required zero-scale power-on reset behavior.

Selection Notes

Select this part when a 4.096V full-scale output is required with an internal reference. The H-grade is necessary for operation above 85°C. Verify that the 4.5V minimum supply voltage aligns with the system power rails. The QFN package requires soldering the exposed pad to PCB ground for thermal management.

Part Context

This component belongs to the LTC2634 family of quad DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset state (zero-scale or mid-scale). The HUD suffix denotes the specific automotive grade and 16-lead QFN package configuration.

Replacement Considerations

Direct substitutes within the same family include LTC2634IUD-LZ12#TRPBF for industrial temperature ranges or LTC2634CUD-LZ12#TRPBF for commercial ranges. Non-quad variants like the LTC2635 use I2C interfaces and are not pin-compatible.
