LTC2636HDE-LMX12#PBF

Overview

The LTC2636HDE-LMX12#PBF is an octal 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 serial interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to mid-scale in external reference mode, and rail-to-rail output buffers. Packaged in a 14-lead DFN, it supports automotive temperature ranges (-40°C to 125°C).

Feature Summary

Octal 12-Bit Resolution: Provides eight independent 12-bit DAC channels with guaranteed monotonicity.
Integrated Precision Reference: Features a 4.096V full-scale internal reference with ±10ppm/°C drift.
Automotive Temperature Grade: Operates reliably within the -40°C to 125°C range.
External Reference Mode: Power-on reset sets outputs to mid-scale based on the external REF pin voltage.

Applications

Process Control and Industrial Automation
Automatic Test Equipment
Portable Equipment

Procurement Notes

Verify the specific suffix LMX12 indicates external reference mode with mid-scale power-on reset. Confirm the H grade ensures operation at 4.5V to 5.5V supplies for the 4.096V full-scale output. Ensure the DE package corresponds to the 14-lead DFN form factor required for the design.

Selection Notes

Select this part when eight high-accuracy 12-bit channels are required in a compact footprint. The H-grade variant is necessary for applications requiring 4.096V full-scale output and automotive temperature compliance. The LMX suffix is critical if system initialization requires outputs to settle at mid-scale relative to an external reference voltage upon power-up.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8/10/12-bit), full-scale voltage (L=2.5V, H=4.096V), and power-on reset behavior (Z=Zero, MI=Mid/Internal, MX=Mid/External). The HDE-LMX12 specifically combines the high-voltage internal reference capability with external reference synchronization and automotive thermal ratings.
