LTC2636IDE-LZ10#TRPBF

Overview

The LTC2636IDE-LZ10#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 includes rail-to-rail output buffers, guaranteed monotonicity, and double-buffered data latches. Communication occurs via a 3-wire SPI/MICROWIRE interface at clock rates up to 50MHz. This specific variant resets to zero-scale upon power-up and 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.
• Zero-Scale Power-On Reset: Outputs initialize to zero-scale upon power-up for consistent system start-up.
• SPI Interface: Supports 3-wire serial communication with SCK frequencies up to 50MHz.

Applications

• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems
• Optical Networking

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 I-grade temperature rating matches the required operational range of -40°C to 85°C for the target application environment.

Selection Notes

Select this part when eight simultaneous analog outputs are required within a compact footprint. The LZ suffix ensures zero-scale initialization, which is critical if downstream circuits must remain inactive during power-up. Compare settling times and linearity specifications against other resolutions if higher precision or speed is needed.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8, 10, or 12 bits), reset behavior (MI for mid-scale, MX for external mid-scale, Z for zero-scale), and package type (DE for DFN, MS for MSOP). The IDE-LZ10 specifically denotes the industrial grade, DFN package, zero-reset, 10-bit configuration.

Replacement Considerations

Direct substitutes include other LTC2636 variants with matching pinouts but different resolutions or reset behaviors, such as LTC2636IDE-LMI10#TRPBF. Cross-family replacements require verification of interface compatibility and output drive capabilities.
