LTC2636HMS-LMI12#TRPBF

Digital To Analog Converters Overview

The LTC2636HMS-LMI12#TRPBF 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 includes rail-to-rail output buffers guaranteed monotonic over the –40°C to 125°C temperature range. Communication occurs via a 3-wire SPI/MICROWIRE-compatible interface supporting clock rates up to 50MHz. Power-on reset defaults to mid-scale in internal reference mode. It is housed in a 16-lead MSOP package.

Digital To Analog Converters Feature Summary

• Octal 12-bit resolution with ±2.5 LSB maximum integral nonlinearity error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Rail-to-rail output buffers with ultralow crosstalk (<2.4nV•s)
• SPI/MICROWIRE compatible 3-wire serial interface operating at 50MHz

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the H-grade automotive temperature rating (-40°C to 125°C) and the specific power-on reset behavior for mid-scale initialization in internal reference mode. Confirm the 16-lead MSOP package configuration matches the design requirements before integration.

Digital To Analog Converters Selection Notes

Select this part when eight independent 12-bit channels are required with high accuracy and low crosstalk. The H-grade variant is necessary for automotive or extended industrial temperature environments. Ensure the system supply voltage remains within the 4.5V to 5.5V range specified for the 4.096V full-scale output configuration.

Digital To Analog Converters Part Context

This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. Variants include L-grade (2.7V–5.5V supply, 2.5V FS) and H-grade (4.5V–5.5V supply, 4.096V FS). Package options are 14-lead DFN and 16-lead MSOP. The #TRPBF suffix indicates tape and reel packaging.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include LTC2636HMS-LMX12#TRPBF (external reference mode) and LTC2636HMS-HZ12#TRPBF (zero-scale reset). For lower resolution needs, consider LTC2636HMS-LMI10#TRPBF or LTC2636HMS-LMI8#TRPBF.
