LTC2636HMS-HZ10#TRPBF

Overview

The LTC2636HMS-HZ10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 4.096V full-scale reference with a 10ppm/°C temperature coefficient. The device operates on a single 4.5V to 5.5V supply and includes rail-to-rail output buffers guaranteed monotonic over the –40°C to 125°C automotive temperature range. Communication occurs via a 50MHz SPI/MICROWIRE-compatible 3-wire serial interface. Power-on reset defaults to zero-scale in internal reference mode. It is housed in a 16-lead MSOP package.

Feature Summary

• Octal 10-Bit Resolution with Rail-to-Rail Output Buffers
• Integrated 4.096V Reference with ±10ppm/°C Drift
• Automotive Grade: –40°C to 125°C Operating Range
• Power-On Reset to Zero-Scale

Applications

• Process Control and Industrial Automation
• Automatic Test Equipment
• Automotive Systems

Procurement Notes

Verify the H-grade automotive temperature rating and Z suffix for zero-scale power-on reset against specific design requirements. Confirm the MSOP-16 package footprint matches the PCB layout. Ensure the 4.5V minimum supply voltage aligns with the system power rails.

Selection Notes

Select this part when eight independent channels are required with high accuracy and automotive reliability. The H-grade variant necessitates a supply voltage of at least 4.5V, unlike the L-grade which supports 2.7V. The Z suffix ensures outputs start at zero upon power-up, suitable for safety-critical initialization sequences.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (L for 2.5V, H for 4.096V), temperature grade (C, I, or H), and power-on reset behavior (MI, MX, or Z). The MSOP package provides hardware clear and LDAC pins not available in the DFN version.
