REF3318AIDCKR

Overview

The REF3318AIDCKR is a precision series voltage reference manufactured by Texas Instruments, delivering a fixed output of 1.8 V. It features an initial accuracy of 0.15% and a temperature coefficient of 30 ppm/°C. The device operates with a quiescent current of 3.9 µA and supports a maximum input voltage of 5.5 V. It provides a maximum shunt current of 5 mA and functions within a temperature range of -40°C to +125°C. The component is housed in a SC-70-3 surface-mount package.

Feature Summary

• Provides stable 1.8 V reference output with high initial accuracy
• Low power consumption suitable for battery-operated systems
• Compact SC-70-3 surface-mount packaging

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement devices
