LTC2636HMS-HMX8#TRPBF

Overview

The LTC2636HMS-HMX8#TRPBF is an octal, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a high-accuracy internal reference with a temperature coefficient of 10ppm/°C and a full-scale output of 4.096V. 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 is handled via a 3-wire SPI/MICROWIRE-compatible interface supporting clock rates up to 50MHz. This specific part number indicates a 16-lead MSOP package, H-grade temperature rating, mid-scale power-on reset in external reference mode, and tape-and-reel packaging.

Feature Summary

• Octal 8-Bit Resolution: Eight independent DAC channels with ±0.5 LSB DNL and ±0.05 LSB INL.
• High-Accuracy Internal Reference: Integrated 10ppm/°C reference providing a 4.096V full-scale output.
• Automotive Temperature Range: Guaranteed monotonic operation from –40°C to +125°C.
• Ultralow Crosstalk: Inter-channel crosstalk specified at less than 2.4nV•s.

Applications

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

Procurement Notes

Verify the suffix #TRPBF confirms the 2500-piece tape and reel packaging format. Confirm the H-grade designation matches the required –40°C to 125°C operating temperature range for the application environment.

Selection Notes

Select this part when eight synchronized 8-bit outputs are required with a 4.096V span. The HMX code specifies a mid-scale reset behavior suitable for systems where downstream circuits must remain active during power-up without zero-scale initialization.

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 package type (DFN or MSOP). The H-grade variant specifically targets automotive applications requiring extended temperature stability.

Replacement Considerations

Direct substitutes within the same family include LTC2636HMI-HMX8#TRPBF (internal reference reset) or LTC2636HZ-HMX8#TRPBF (zero-scale reset). Cross-package equivalents like the DE (DFN) version require schematic review for pin compatibility.
