ADR520/ADR525/ADR530/ADR540/ADR550 is a series of ultra-compact precise voltage references with six output voltages of 2.048V, 2.5V, 3.0V, 3.3V, 4.0V and 5.0V, maximum temperature coefficient of 40ppm/°C, initial accuracy of ±0.2%. It is suitable for portable, battery-powered equipment, automotive, power supplies, data acquisition systems, instrumentation and process control, energy measurement and other applications.
The ADR520/ADR525/ADR530/ADR540/ADR550 are high precision shunt voltage references housed in ultrasmall SC70 and SOT-23-3 packages. These devices feature a low temperature drift of 40 ppm/°C, an initial accuracy better than +0.2%, and ultralow output noise of 14 µV p-p for the ADR520 series.
Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V, the advanced design eliminates the need for compensation by an external capacitor while remaining stable with any capacitive load. The minimum operating current ranges from a mere 50 µA to a maximum of 15 mA.
