ADR512ART-REEL7

Overview

The ADR512ARTZ-REEL7 is a precision shunt voltage reference delivering a nominal output of 1.200 V in an ultracompact 3-Lead SOT-23 package. It features an initial accuracy of ±0.3% and a maximum temperature coefficient of 60 ppm/°C across the −40°C to +85°C operating range. The device operates within a current range of 100 µA to 10 mA, exhibits low output noise of 4 µV p-p (0.1 Hz to 10 Hz), and maintains a dynamic output impedance of 0.3 Ω max without requiring external stabilization capacitors.

Feature Summary

• Ultracompact 3 mm × 3 mm SOT-23 package designed for space-critical applications
• Advanced design ensures stability with any capacitive load without external capacitors
• Integrated TRIM terminal allows output voltage adjustment over ±0.5% without affecting temperature coefficient

Applications

• Precision data acquisition systems
• Battery-powered equipment including cellular phones, notebook computers, PDAs, and GPS devices
• 3 V/5 V, 8-/12-bit data converters
• Portable medical instruments
• Industrial process control systems

Procurement Notes

Verify the specific ordering suffix ARTZ-REEL7 against the manufacturer's official documentation to confirm reel quantity and tape specifications. Ensure compatibility with surface-mount assembly processes for the 3-Lead SOT-23 package. Confirm that the selected variant meets the required initial accuracy and temperature coefficient grades for the intended application environment.

Selection Notes

Select this component when a low-voltage, high-precision reference is needed in minimal footprint designs. The absence of external capacitor requirements simplifies layout and reduces bill of materials. Consider the 100 µA minimum operating current for battery life optimization in portable devices. Verify that the bias resistor network supports the full 10 mA maximum current capability under worst-case supply conditions.

Part Context

The ADR512 belongs to Analog Devices' family of precision shunt voltage references. It serves as a compact alternative to traditional Zener diodes or larger package references. The device integrates advanced bandgap technology to achieve low drift and noise in a small outline transistor package suitable for handheld electronics.

Replacement Considerations

Check the manufacturer's official replacement guide for direct pin-compatible alternatives. Verify that substitute parts match the 1.2 V output, SOT-23-3 package, and ±0.3% accuracy grade. Ensure thermal resistance and operating current ranges are compatible with existing circuit designs.
