LTC2637HDE-HMX8#PBF

Overview

The LTC2637HDE-HMX8#PBF is an octal 8-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 a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches, rail-to-rail output buffers, and a power-on reset circuit configured to reset to mid-scale in external reference mode.

Feature Summary

Octal architecture with 8 independent 8-bit DAC channels
Integrated 4.096V precision reference with ±10ppm/°C drift
I2C serial interface with selectable slave addresses via CA0-CA2 pins
Power-on reset to mid-scale for external reference configurations

Applications

Process control and industrial automation systems
Automatic test equipment requiring multi-channel signal generation
Portable battery-powered instrumentation
Automotive electronic control units

Procurement Notes

Verify the specific suffix HDE against official documentation to confirm package type and lead finish. Ensure the external reference configuration matches the MX power-on reset behavior. Confirm availability through authorized distributors as stock levels vary by region.

Selection Notes

Select this part when eight low-cost, low-resolution channels are required with high integration. The H-grade ensures operation up to 125°C. Verify that the 4.096V internal reference range suits the application or if an external reference is preferred for different full-scale voltages.

Part Context

This component belongs to the LTC2637 family, which includes 12-bit, 10-bit, and 8-bit variants. The 'H' designation indicates automotive-grade temperature performance (-40°C to 125°C), while 'DE' specifies the 14-lead DFN package. The 'MX' suffix defines the power-on reset behavior for external reference modes.

Replacement Considerations

LTC2637IDE-HMX8#PBF offers identical electrical specifications but in the Industrial temperature grade (-40°C to 85°C). Other family members like LTC2637HMI8 provide different reset behaviors.
