LTC2636IMS-HZ10#PBF

Overview

The LTC2636IMS-HZ10#PBF 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 temperature range, and double-buffered data latches. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. This specific variant resets to zero-scale upon power-up and is housed in a 16-lead MSOP package.

Feature Summary

• Octal 10-bit resolution with integrated 4.096V internal reference
• Rail-to-rail output buffers with guaranteed monotonicity
• SPI/MICROWIRE compatible 3-wire serial interface (up to 50MHz)
• Power-on reset to zero-scale in internal reference mode

Applications

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

Procurement Notes

Verify the component matches the specified 16-lead MSOP package and H-grade automotive temperature rating (-40°C to 125°C). Confirm the ordering suffix indicates zero-scale power-on reset behavior. Ensure compatibility with the required 4.5V to 5.5V supply voltage range for proper operation.

Selection Notes

Select this part when eight independent DAC channels are required with high accuracy and low drift. The H-grade version supports wider temperature ranges compared to C or I grades. Choose this model if a 4.096V full-scale output is needed; otherwise, consider the L-grade for 2.5V outputs. Verify that the MSOP package pinout fits the PCB layout constraints.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset behavior (zero-scale or mid-scale). The IMS designation specifically denotes the Industrial/Automotive temperature grade and MSOP packaging.

Replacement Considerations

Direct replacements within the same family include LTC2636IMS-HZ12#PBF (12-bit) or LTC2636IMS-HZ8#PBF (8-bit). For different reset behaviors, consider LTC2636IMS-HMI10#PBF. Cross-family alternatives like the LTC2637 offer I2C interfaces but require pinout and software adaptation.
