LTC2637HDE-LMX10#TRPBF

Overview

The LTC2637HDE-LMX10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a 4.096V full-scale output with a temperature coefficient of 10ppm/°C. The device operates on a single 4.5V to 5.5V supply and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches, power-on reset functionality set to mid-scale for external reference mode, and rail-to-rail output buffers guaranteed monotonic over the automotive temperature range of –40°C to 125°C.

Feature Summary

Octal 10-bit resolution with integrated 4.096V precision reference
I2C-compatible serial interface with selectable slave addresses
Power-on reset to mid-scale in external reference mode
Automotive grade operation (-40°C to 125°C)

Applications

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

Procurement Notes

Verify that the specific suffix LMX10 corresponds to the intended power-on reset behavior (mid-scale in external reference mode) and the 10-bit resolution. Confirm the H-grade designation matches the required 4.096V internal reference and 4.5V minimum supply voltage. Ensure the DE package (14-lead DFN) aligns with the PCB footprint requirements.

Selection Notes

Select this part when eight independent voltage outputs are required with high accuracy and low crosstalk. The H-grade variant is necessary for applications requiring a 4.096V full-scale range and operation up to 125°C. The LMX suffix is critical if the system design requires the DAC outputs to initialize at mid-scale during power-up when using an external reference source.

Part Context

This component belongs to the LTC2637 family of octal DACs, which also includes 8-bit and 12-bit variants. The family shares common architectural features such as the I2C interface and low-power consumption but differs in resolution, full-scale voltage options (L vs. H grades), and package types (DFN vs. MSOP).
