LTC2634HMSE-HZ8#TRPBF

Overview

The LTC2634HMSE-HZ8#TRPBF is a quad 8-bit voltage output digital-to-analog converter (DAC) from Analog Devices Inc. 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, double-buffered data latches, and ultralow crosstalk between channels. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. This specific variant is housed in a 10-lead MSOP package and incorporates a power-on reset circuit that defaults outputs to zero-scale.

Feature Summary

• Quad 8-bit resolution with 4.096V full-scale output using internal reference
• Integrated 10ppm/°C precision reference with selectable external reference input
• Rail-to-rail output buffers guaranteed monotonic over -40°C to 125°C
• Power-on reset to zero-scale in internal reference mode

Applications

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

Procurement Notes

Verify the ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the H temperature grade meets the required -40°C to 125°C operating range for the target application environment.

Selection Notes

Select this part when four independent 8-bit DACs are required in a compact surface-mount package. The HMSE suffix denotes the high-grade automotive temperature range (-40°C to 125°C) and MSOP packaging. Choose the H variant for 4.096V full-scale applications requiring a 4.5V minimum supply voltage.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The family shares common architecture including rail-to-rail outputs and low drift references but differs in accuracy specifications and package options such as 16-lead QFN or 10-lead MSOP.

Replacement Considerations

Direct pin-compatible replacements within the same package include other LTC2634 variants with different resolutions or reset behaviors, provided the electrical parameters meet system requirements.
