ADR434BRZ, Voltage Reference IC, 3ppm/°C, 4.096V, 1.5mV, Series, NSOIC-8, -40°C to 125°C

Полупроводники - Микросхемы\Микросхемы Управления Питанием\Источники Опорного НапряженияADR434 series is a family of XFET® voltage reference featuring low noise, high accuracy and low temperature drift performance. Using Analog Devices, Inc., temperature drift curvature correction and extra implanted junction FET (XFET) technology, voltage change vs. temperature nonlinearity in device is minimized. The XFET references operate at lower current (800µA) and lower supply voltage headroom (2V) than buried zener references. Buried zener references require more than 5V of headroom for operation. The device XFET reference is low noise solution for 5V systems. It has the capability to source up to 30mA of output current and sink up to -20mA. It also comes with a trim terminal to adjust the output voltage over a ±0.5% range without compromising performance. Applications include precision data acquisition systems, high resolution data converters, medical instruments, industrial process control systems, optical control circuits and precision instruments. • Ultralow noise XFET voltage reference with current sink and source capability• Wide temperature range from -40°C to +125°C• Wide operating range from 6.1V to 18V• 4.096V output voltage typ, ±1.5mV/ ±0.04% initial accuracy, 3ppm/°C temperature coefficient package• No external capacitor required• Line regulation of 20ppm/V at VIN = 6.1V to 18V, -40°C < TA < +125°C• Load regulation of 15ppm/mA at IL = 0mA to 10mA, VIN = 7V, -40°C < TA < +125°C• Low noise (0.1Hz to 10Hz) of 6.25µV p-p• Turn-on settling time of 10µs at CL = 0µF• 8-lead SOIC• N package
