LTC2636CMS-HMI12#TRPBF

Overview

The LTC2636CMS-HMI12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a high-accuracy internal reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single 4.5V to 5.5V supply and utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to mid-scale in internal reference mode, and rail-to-rail output buffers guaranteed monotonic over the operating range.

Feature Summary

• Octal 12-bit resolution with ±2.5LSB maximum integral nonlinearity error
• Integrated 10ppm/°C reference yielding 4.096V full-scale output
• SPI/MICROWIRE compatible 3-wire serial interface supporting 50MHz clock
• Power-on reset configured for mid-scale output in internal reference mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive applications
• Optical networking

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the MS package designation corresponds to the 16-lead MSOP form factor. Ensure the H-grade temperature rating matches the required operational environment of -40°C to 125°C before procurement.

Selection Notes

Select this part when eight independent 12-bit channels are required with a fixed 4.096V span. The H-grade variant necessitates a supply voltage between 4.5V and 5.5V, unlike the L-grade which supports 2.7V. Choose the MI suffix if mid-scale initialization upon power-up is preferred over zero-scale or external reference modes.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The CMS designation identifies the 16-lead MSOP package option, distinct from the 14-lead DFN DE package. The H suffix denotes the automotive temperature grade (-40°C to 125°C) and higher supply voltage requirements compared to commercial or industrial grades.

Replacement Considerations

Public confirmed substitute part numbers: None.
