LTC2636HMS-LZ10#TRPBF

Overview

The LTC2636HMS-LZ10#TRPBF is an octal 10-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 monotonicity over the –40°C to 125°C automotive temperature range, and a 3-wire SPI/MICROWIRE compatible serial interface. It incorporates a power-on reset circuit that clears outputs to zero-scale upon initialization.

Feature Summary

• Octal 10-Bit Resolution: Provides eight independent DAC channels with 10-bit accuracy.
• Integrated Precision Reference: Features a 10ppm/°C internal reference setting a 4.096V full-scale output.
• Automotive Temperature Grade: Operates reliably within the –40°C to 125°C extended temperature range.
• Zero-Scale Power-On Reset: Outputs initialize to zero-scale upon power-up for consistent system start-up.

Applications

• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment

Procurement Notes

Verify the specific 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 specification matches the required 4.5V to 5.5V supply voltage constraints for the target application environment.

Selection Notes

Select this part when eight isolated analog outputs are required in a compact footprint. The H-grade variant is necessary for applications demanding operation above 85°C or requiring the 4.096V internal reference span. The LZ suffix ensures zero-scale initialization, which is critical if downstream circuits must remain inactive during power sequencing.

Part Context

This component belongs to the LTC2636 family of octal DACs, which also offers 8-bit and 12-bit resolutions. Variants include the LTC2636L series for 2.5V full-scale operation and lower voltage supplies. The MSOP package provides exposed pad thermal management, distinguishing it from the smaller DFN option while maintaining similar electrical performance characteristics.

Replacement Considerations
