LTC2636CDE-LMI10#TRPBF

Overview

The LTC2636CDE-LMI10#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 utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to mid-scale, and rail-to-rail output buffers guaranteed monotonic over the temperature range. Packaged in a 14-lead DFN.

Feature Summary

• Octal 10-Bit Resolution with ±1 LSB Integral Nonlinearity
• Integrated 2.5V Full-Scale Reference (10ppm/°C)
• Power-On Reset to Mid-Scale in Internal Reference Mode
• Rail-to-Rail Output Buffers with Ultralow Crosstalk (<2.4nV•s)

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2500 pieces. Confirm the DE package designation corresponds to the 14-lead DFN form factor. Ensure the LMI10 code matches the required 10-bit resolution and mid-scale power-on reset behavior for the design.

Selection Notes

Select this part when eight independent 10-bit channels are required with a fixed 2.5V internal reference. The C-grade temperature range covers 0°C to 70°C. Choose the MSOP package if hardware CLR and LDAC pins are necessary, as these are exclusive to the 16-lead variant.

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 power-on reset behavior (zero-scale or mid-scale). The CDE-LMI10 specifically denotes the commercial grade, DFN package, and mid-scale reset configuration.

Replacement Considerations

Direct substitutes within the same family include LTC2636CDE-LMX10#TRPBF (external reference mode) or LTC2636CDE-LZ10#TRPBF (zero-scale reset). For higher precision, consider the 12-bit variants such as LTC2636CDE-LMI12#TRPBF.
