2 V Precision Low Noise Shunt Voltage Reference ADR512 FEATURES Precision 1.
200 V Voltage Reference Ultracompact 3 mm × 3 mm SOT-23 Package No External Capacitor Required Low Output Noise: 4 µV p-p (0.
1 Hz to 10 Hz) Initial Accuracy: ±0.
3% Max Temperature Coefficient: 60 ppm/°C Max Operating Current Range: 100 µA to 10 mA Output Impedance: 0.
3 Ω Max Temperature Range: −40°C to +85°C APPLICATIONS Precision Data Acquisition Systems Battery-Powered Equipment: Cellular Phone, Notebook Computer, PDA, and GPS 3 V/5 V, 8-/12-Bit Data Converters Portable Medical Instruments Industrial Process Control Systems Precision Instruments GENERAL DESCRIPTION Designed for space critical applications, the ADR512 is a low voltage (1.
200 V), precision shunt-mode voltage reference in the ultracompact (3 mm × 3 mm) SOT-23 package.
The ADR512 features low temperature drift (60 ppm/°C), high accuracy (±0.
30%), and ultralow noise (4 µV p-p) performance.
The ADR512’s advanced design eliminates the need for an external capacitor, yet it is stable with any capacitive load.
The minimum operating current increases from a scant 100 µA to a PIN CONFIGURATION V+ 1 ADR512 03700-001 3 TRIM/NC V– 2 TOP VIEW (Not to Scale) NC = NO CONNECT.
DO NOT CONNECT TO THIS PIN.

3 Temperature Coefficient (ppm/°C) 60 maximum of 10 mA.
This low operating current and ease of use make the ADR512 ideally suited for handheld battery-powered applications.
A TRIM terminal is available on the ADR512 to provide adjustment of the output voltage over ±0.
5% without affecting the temperature coefficient of the device.
This feature provides users with the flexibility to trim out any system errors.
