LTC2634HMSE-HZ10#TRPBF

Overview

The LTC2634HMSE-HZ10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a 4.096V full-scale output 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 power-on reset to zero-scale. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. It is housed in a 10-lead MSOP package.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference
• Rail-to-rail output buffers with guaranteed monotonicity
• Automotive grade (-40°C to 125°C) with AEC-Q100 qualification
• Power-on reset to zero-scale for consistent initialization

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the H-grade designation matches the required -40°C to 125°C operating temperature range. Ensure the Z-power-on reset configuration aligns with system startup requirements. Check for lead-free compliance status.

Selection Notes

Select this part when a quad 10-bit resolution is required with a fixed 4.096V internal reference. The HMSE package denotes the 10-lead MSOP form factor. Choose the H-grade for automotive applications requiring extended temperature ranges. Verify that the 4.5V minimum supply voltage fits the system design constraints.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 8-, 10-, and 12-bit resolutions. The family shares similar architectural features but varies in accuracy, full-scale voltage options (2.5V or 4.096V), and package types (QFN or MSOP). The HZ10 variant specifically targets high-precision automotive applications requiring zero-scale reset behavior.

Replacement Considerations

Compatible substitutes within the same family include LTC2634IMSE-HZ10#PBF for tube packaging or other resolution variants like LTC2634HMSE-HZ12#TRPBF if higher precision is needed. Cross-package replacements require pinout verification between MSOP and QFN formats.
