FEATURES Precision 1.000 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: ±0.35% maximum Temperature coefficient: 70 ppm/°C maximum Operating current range: 100 μA to 10 mA Output impedance: 0.3 Ω maximum Temperature range: −40°C to +85°C APPLICATIONS Precision data acquisition systems Battery-powered equipment Cellular phone Notebook computer PDA GPS 3 V/5 V, 8-/12-bit data converters Portable medical instruments Industrial process control systems Precision instruments PIN CONFIGURATION NC = NO CONNECT V+ 1 V– 2 TRIM/NC 3 ADR510 TOP VIEW (Not to Scale) Figure 1. 3-Lead SOT-23-3 GENERAL DESCRIPTION Designed for space critical applications, the ADR510 is a low voltage (1.000 V), precision shunt-mode voltage reference in an ultracompact (3 mm × 3 mm) SOT-23-3 package. The ADR510 features low temperature drift (70 ppm/°C), high accuracy (±0.35%), and ultralow noise (4 μV p-p) performance. The ADR510 advanced design eliminates the need for an external capacitor, yet it is stable with any capacitive load. The minimum operating current increases from 100 μA to a maximum of 10 mA. This low operating current and ease of use make the ADR510 ideally suited for handheld battery-powered applications. A TRIM terminal is available on the ADR510 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. VS IL + IQ IQ COUT (OPTIONAL) VOUT = 1.0V RBIAS IL ADR510 IL + IQ VS – VOUT RBIAS = Figure 2.
