LTC2635HUD-LMX12#PBF

Overview

The LTC2635HUD-LMX12#PBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in a 16-lead QFN package. 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 includes rail-to-rail output buffers 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. Power-on reset options include mid-scale initialization for external reference configurations.

Feature Summary

Quad 12-bit resolution with maximum INL error of ±2.5 LSB
Integrated 4.096V full-scale reference with 10ppm/°C drift
Automotive temperature grade (-40°C to 125°C)
Power-on reset to mid-scale in external reference mode

Applications

Process control and industrial automation
Power supply margining
Portable equipment

Procurement Notes

Verify the specific suffix 'LMX' indicates power-on reset to mid-scale when using an external reference. Confirm the 'H' designation ensures compatibility with the required 4.5V to 5.5V supply range. Ensure the QFN package thermal pad is properly soldered to the PCB ground plane for optimal performance and reliability.

Selection Notes

Select this part when a 4.096V internal reference is required alongside strict linearity specifications. The LMX variant is appropriate if mid-scale initialization upon power-up is preferred over zero-scale or high-impedance states. Verify that the system supply voltage remains within the 4.5V to 5.5V window to meet all electrical characteristics.

Part Context

This component belongs to the LTC2635 family of quad DACs, which also offers 8-bit and 10-bit resolutions. The 'H' suffix distinguishes it from the 'L' variant by providing a higher 4.096V full-scale output and requiring a minimum 4.5V supply, whereas the 'L' version provides 2.5V and operates down to 2.7V.
