Overview
The ADR510ARTZ-R2 is a 1.000 V precision shunt voltage reference in an ultracompact 3 mm × 3 mm SOT-23-3 package. It features ±0.35% initial accuracy, 70 ppm/°C temperature coefficient (85 ppm/°C over -40°C to +85°C), and 4 μV p-p noise (0.1 Hz to 10 Hz). Operating current ranges from 100 μA to 10 mA without external capacitors. Output impedance is 0.3 Ω maximum. The device includes a TRIM pin for ±0.5% output adjustment.
Feature Summary
- Ultracompact 3 mm × 3 mm SOT-23-3 package designed for space-critical applications
- Advanced design eliminates the need for an external capacitor while maintaining stability with any capacitive load
- TRIM terminal allows ±0.5% output voltage adjustment without affecting the temperature coefficient
Applications
- Precision data acquisition systems
- Battery-powered equipment
- Cellular phones
- Portable medical instruments
- Industrial process control systems
Procurement Notes
Verify the specific ordering suffix R2 indicates a 250-unit cut tape quantity rather than reel packaging. Confirm RoHS compliance status associated with the Z suffix. Ensure the selected variant matches the required temperature range and accuracy grade for the target application environment.
Selection Notes
Select this component when a low-voltage, high-precision reference is needed in minimal footprint designs. The fixed 1.000 V output suits single-supply or dual-supply biasing. Consider the 100 μA minimum operating current for battery life optimization. Verify that the 10 mA maximum current capability meets the system's bias resistor requirements.
Part Context
The ADR510 belongs to Analog Devices' family of precision shunt voltage references. It utilizes advanced bandgap technology to achieve low drift and noise. The RT-3 package option provides a compact surface-mount solution suitable for portable electronics and handheld devices requiring stable voltage references.
Replacement Considerations
ADR510ART-REEL7: Identical electrical specifications; differs only in reel packaging quantity (3,000 units vs. 250 units).
FAQ
Does the ADR510 require an external capacitor for stability?
No, the ADR510 is designed to operate stably without an external capacitor between its positive and negative terminals, though one can be added for additional filtering.
How does the temperature coefficient vary across the operating range?
The temperature coefficient is specified as 70 ppm/°C maximum between 0°C and 70°C, and increases to 85 ppm/°C maximum over the full -40°C to +85°C operating range.
