LTC2636IDE-LMX10#TRPBF

Overview

The LTC2636IDE-LMX10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 10ppm/°C reference with a full-scale output of 2.5V and operates on a single 2.7V to 5.5V supply. The device communicates via a 3-wire SPI/MICROWIRE-compatible interface supporting 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 temperature range. This specific part is housed in a 14-lead DFN package.

Feature Summary

• Octal 10-Bit Resolution: Provides eight independent DAC channels with 10-bit precision.
• Integrated Reference: Features a low-drift 10ppm/°C internal reference setting a 2.5V full-scale output.
• SPI Interface: Compatible with standard SPI and MICROWIRE protocols at speeds up to 50MHz.
• Power-On Reset: Configured to reset outputs to mid-scale when operating in external reference mode.

Applications

• Process Control and Industrial Automation
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the 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 LMX10 code matches the required 10-bit resolution and mid-scale external reference reset behavior for the design.

Selection Notes

Select this component when eight simultaneous voltage outputs are required with 10-bit accuracy. The 2.5V internal reference suits applications needing lower voltage swings compared to the 4.096V H-grade variants. The industrial temperature grade (-40°C to 85°C) is suitable for broader environmental conditions than the commercial C-grade parts.

Part Context

This part belongs to the LTC2636 family of octal DACs. Variations exist based on resolution (8, 10, or 12 bits), package type (DFN or MSOP), and temperature grade (C, I, or H). The IDE suffix specifically denotes the Industrial temperature range and 14-lead DFN package configuration.

Replacement Considerations

Direct substitutes include other LTC2636 variants with matching 10-bit resolution and DFN packaging, such as LTC2636CDE-LMX10#TRPBF for commercial temperature ranges. Cross-package replacements like the MSOP version require pinout verification due to additional control pins.
