LTC2637HDE-LMX8#PBF

Overview

The LTC2637HDE-LMX8#PBF is an octal 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a high-accuracy, low-drift internal reference with a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches and a power-on reset circuit configured to reset to mid-scale in external reference mode. The unit is housed in a 14-lead 4mm × 3mm DFN package.

Feature Summary

Octal 8-Bit Resolution: Provides eight independent DAC channels with guaranteed monotonicity over the operating temperature range.
Integrated Precision Reference: Includes a 4.096V full-scale internal reference with a temperature coefficient of 10ppm/°C.
I2C Interface: Supports standard and fast mode clock rates up to 400kHz for efficient serial communication.
Power-On Reset: Configured for mid-scale reset in external reference mode upon power-up.

Applications

Mobile Communications
Process Control and Industrial Automation
Automatic Test Equipment
Portable Equipment
Automotive Systems

Procurement Notes

Verify the specific ordering suffix LMX8 confirms the mid-scale reset behavior in external reference mode. Ensure the H-grade designation matches the required 4.5V to 5.5V supply voltage range. Confirm the DE package type corresponds to the 14-lead DFN footprint required for the design.

Selection Notes

Select this part when eight isolated voltage outputs are needed with minimal crosstalk. The H-grade variant is suitable for applications requiring a 4.096V full-scale range powered by a 5V supply. Consider the L-grade if a lower 2.7V to 5.5V supply range or 2.5V full-scale output is preferred.

Part Context

This component belongs to the LTC2637 family, which includes 12-, 10-, and 8-bit variants. The H-suffix indicates the automotive temperature grade (-40°C to 125°C) and the 4.096V internal reference configuration. The DE suffix specifies the 14-lead plastic DFN package.
