REF03GP

Overview

The REF03GP is a precision voltage reference from Analog Devices Inc. featuring a fixed 2.5 V output with ±0.6% maximum tolerance. It operates within an input voltage range of 4.5 V to 33 V and draws a maximum supply current of 1.4 mA. The device exhibits a temperature coefficient of 50 ppm/°C, line regulation of 50 ppm/V, and load regulation of 100 ppm/mA. It supports sourcing up to 10 mA and sinking up to 0.5 mA. Operating temperatures span −40°C to +85°C. Available in 8-lead PDIP (P-Suffix) packages.

Feature Summary

• Provides stable 2.5 V output using improved band gap design
• Supports single-supply operation over wide input voltage range
• Includes trimmable resistor for output voltage adjustment

Applications

• Data conversion circuits requiring absolute reference points
• Logarithmic amplifiers
• 4 mA to 20 mA transmitters
• CMOS DAC references

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and compliance status. Confirm availability as manufacturing schedules may change. Ensure environmental specifications align with project requirements before finalizing procurement decisions.

Selection Notes

Select this component when a low-cost, stable 2.5 V reference is required for industrial applications. Consider the ±0.6% initial accuracy and 50 ppm/°C temperature stability for systems sensitive to supply variations. Evaluate the need for external current boosting if loads exceed the internal 10 mA sourcing capability.

Part Context

The REF03 series provides precision voltage references designed for cost-sensitive applications. The REF03GP specifically utilizes an 8-lead plastic dual in-line package. This family targets systems needing reliable performance across extended industrial temperature ranges without requiring complex external compensation circuitry.
