REF02DPZ

Overview

The REF02DPZ is a precision voltage reference from Analog Devices Inc. providing a fixed 5 V output with ±100 mV initial accuracy (±2%). It features an 8.5 ppm/°C temperature coefficient and operates over a 0°C to +70°C range. The device accepts input voltages from 7 V to 40 V, draws 1.6 mA quiescent current, and supplies up to 8 mA load current. It includes a dedicated temperature monitoring pin.

Feature Summary

• Integrated monolithic band gap design delivering stable 5 V reference without external components
• Dedicated temperature sensing terminal providing linear voltage variation for system monitoring
• Short-circuit protection capability allowing indefinite duration when connected to ground or input

Applications

• Digital-to-Analog Converter (DAC) references
• Analog-to-Digital Converter (ADC) references
• Portable instrumentation systems
• Temperature monitoring circuits

Procurement Notes

Verify the specific suffix 'DPZ' against the manufacturer's ordering guide to confirm package type and lead-free status. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range. Confirm that the required load current does not exceed the 8 mA maximum rating for this specific grade.

Selection Notes

Select the REF02DPZ when a fixed 5 V reference with ±2% initial accuracy is sufficient. This model is suitable for commercial applications requiring operation between 0°C and +70°C. Consider higher grades like REF02A if tighter accuracy or wider industrial temperature ranges are necessary.

Part Context

The REF02 belongs to a family of precision voltage references designed for single-supply operation. It utilizes an improved band gap architecture to achieve low noise and low power consumption. The component serves as a foundational reference element in mixed-signal systems where stability and cost-effectiveness are prioritized.
