LTC2636IDE-LMX10#PBF

Overview

The LTC2636IDE-LMX10#PBF 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 50MHz SPI-compatible interface and includes double-buffered data latches. It guarantees monotonicity over the industrial temperature range of –40°C to 85°C. The part is housed in a 14-lead 4mm × 3mm DFN package and powers up to mid-scale in external reference mode.

Feature Summary

• Octal 10-Bit Resolution: Provides eight independent DAC channels with ±1 LSB integral nonlinearity error.
• Integrated Reference: Features a low-drift 10ppm/°C internal reference setting a 2.5V full-scale output.
• Power-On Reset: Configured for mid-scale reset in external reference mode upon power-up.
• Industrial Temperature Range: Guaranteed operation from –40°C to 85°C.

Applications

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

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current documentation to confirm package type, temperature grade, and reset configuration. Ensure the component matches the required 14-lead DFN footprint and that the external reference mode power-on behavior aligns with system initialization requirements.

Selection Notes

Select this part when eight independent 10-bit outputs are required within a compact DFN footprint. The L-series designation indicates a 2.5V full-scale range compatible with 2.7V supplies. The MX suffix specifies mid-scale reset in external reference mode; choose MI for internal reference mode or Z for zero-scale reset if different startup states are needed.

Part Context

This component belongs to the LTC2636 family of octal DACs, which also offers 8-bit and 12-bit resolutions. Variants include the H-series for 4.096V full-scale outputs requiring higher supply voltages. The DE package denotes the 14-lead DFN form factor, while MS packages provide 16 leads with additional control pins.
