ADR510ARTZ-REEL7

Overview

The ADR510ARTZ-REEL7 is a precision shunt voltage reference providing a nominal output of 1.000 V in an ultracompact 3 mm × 3 mm SOT-23-3 package. It features a maximum initial accuracy of ±0.35% and a temperature coefficient of 70 ppm/°C within the 0°C to 70°C range, extending to 85 ppm/°C across the full -40°C to +85°C operating range. The device operates with an input current between 100 μA and 10 mA without requiring an external capacitor for stability. Key electrical parameters include a dynamic output impedance of 0.3 Ω maximum and low output noise of 4 μV p-p from 0.1 Hz to 10 Hz.

Feature Summary

• Ultralow noise performance with 4 μV p-p output noise in the 0.1 Hz to 10 Hz frequency band.
• Advanced design eliminates the need for an external output capacitor while maintaining stability with any capacitive load.
• Integrated TRIM terminal allows for ±0.5% output voltage adjustment without affecting the temperature coefficient.
• Compact 3-Lead SOT-23-3 package designed for space-critical applications.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as the datasheet lists both REEL7 (3,000 units) and R2 (250 units) options. Confirm RoHS compliance status indicated by the 'Z' suffix in the part number. Ensure the selected variant meets the specific temperature coefficient requirements for the intended operating environment.

Selection Notes

Select this component when a compact footprint and low quiescent current are critical constraints. The device is suitable for applications requiring a stable 1.0 V reference without external filtering components. Consider the TRIM pin functionality if system-level calibration is necessary to compensate for board-level errors or initial tolerance variations.

Part Context

The ADR510 belongs to Analog Devices' family of precision shunt voltage references. It is specifically engineered for handheld and portable electronics where power efficiency and physical size are limiting factors. The device serves as a direct replacement for larger discrete Zener diode solutions or bulkier series reference topologies in low-voltage signal chains.
