LTC2637IDE-HMX8#TRPBF

Digital To Analog Converters Overview

The LTC2637IDE-HMX8#TRPBF is an octal 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a high-accuracy internal reference with a 10ppm/°C temperature coefficient, providing a full-scale output of 4.096V. The device operates on a single 4.5V to 5.5V supply and utilizes a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±0.5 LSB, a settling time of 3.9µs at ±1 LSB, and a power-on reset function configured to mid-scale in external reference mode.

Digital To Analog Converters Feature Summary

• Octal architecture with 8 independent 8-bit DAC channels
• Integrated precision reference yielding 4.096V full-scale output
• Ultralow DAC-to-DAC crosstalk specification (<3nV•s)
• Double-buffered data latches for glitch-free updates

Digital To Analog Converters Applications

• Process control and industrial automation systems
• Automatic test equipment requiring multi-channel signal generation
• Portable battery-powered instrumentation
• Optical networking components

Digital To Analog Converters Procurement Notes

Verify the H-grade automotive temperature rating (-40°C to 125°C) and the MX suffix configuration for power-on reset behavior. Confirm the MSOP-16 package type matches the target PCB footprint. Ensure the I2C address pins are correctly terminated to avoid bus conflicts in multi-device designs.

Digital To Analog Converters Selection Notes

Select this part when eight isolated voltage outputs are required within a compact footprint. The H-grade variant supports higher supply voltages up to 5.5V compared to the L-grade. Consider the external reference mode capability if system-level calibration or specific voltage scaling is necessary beyond the internal 4.096V limit.

Digital To Analog Converters Part Context

This component belongs to the LTC2637 family, which includes 12-bit, 10-bit, and 8-bit variants. The 'I' designation indicates the industrial temperature range, while 'H' specifies the extended automotive grade. The '#TRPBF' suffix denotes tape and reel packaging with lead-free composition.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include LTC2637IMS-HMX8#TRPBF (identical specs, different manufacturer source code potentially) or other resolution variants like LTC2637IMS-HMX10#TRPBF if higher precision is acceptable.
