LTC2636CMS-HMX12#TRPBF

Overview

The LTC2636CMS-HMX12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 4.096V full-scale output with an internal reference and operates on a 4.5V to 5.5V supply. The device includes double-buffered data latches, ultralow crosstalk between DACs (<2.4nV•s), and guaranteed monotonicity over the –40°C to 125°C temperature range. It communicates via a 50MHz SPI-compatible 3-wire serial interface and powers up to mid-scale in external reference mode.

Feature Summary

• Octal 12-bit resolution with rail-to-rail output buffers
• 4.096V full-scale output using internal reference
• Ultralow DAC-to-DAC crosstalk (<2.4nV•s)
• Guaranteed monotonic operation from –40°C to 125°C

Applications

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

Procurement Notes

Verify the specific ordering suffix HMX12 against the official datasheet to confirm power-on reset behavior and full-scale voltage specifications. Ensure the MSOP-16 package variant matches the design requirements for thermal resistance and pin configuration.

Selection Notes

Select this part when eight independent 12-bit channels are required with high accuracy and low crosstalk. The H-grade ensures performance across the automotive temperature range. Verify that the 4.5V minimum supply voltage aligns with the system power architecture.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. Variants differ by full-scale voltage (2.5V or 4.096V), power-on reset state, and operating temperature grade. The CMS designation indicates the 16-lead MSOP package form factor.

Replacement Considerations

Public confirmed substitute part numbers: None.
