LTC2636HDE-LMX8#TRPBF

Overview

The LTC2636HDE-LMX8#TRPBF is an octal, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated internal reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and communicates via a 3-wire SPI/Microwire-compatible interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to mid-scale in external reference mode, and rail-to-rail output buffers guaranteed monotonic over the automotive temperature range of –40°C to 125°C.

Feature Summary

Octal 8-Bit Architecture: Eight independent DAC channels with rail-to-rail output buffers.
Integrated Reference: Internal 10ppm/°C reference sets full-scale output to 4.096V.
Automotive Grade: Guaranteed monotonic operation from –40°C to 125°C.
Power-On Reset: Resets outputs to mid-scale upon power-up in external reference mode.

Applications

Process Control and Industrial Automation
Automatic Test Equipment
Portable Equipment

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the DE package designation corresponds to the 14-lead DFN form factor. Ensure the H-grade specification matches the required 4.5V to 5.5V supply range for your application design.

Selection Notes

Select this part when eight isolated analog outputs are required within a compact footprint. The H-grade variant is necessary for applications demanding a 4.096V full-scale range and operation up to 125°C. The LMX suffix specifies mid-scale reset behavior suitable for systems where downstream circuits must remain active during initialization.

Part Context

This component belongs to the LTC2636 family of octal DACs, which also offers 10-bit and 12-bit resolutions. Variants include the LTC2636L series for 2.5V full-scale operation and the LTC2637 series utilizing I2C interfaces instead of SPI. The HDE-LMX8 configuration specifically targets high-reliability industrial environments requiring precise voltage generation.
