ADR392AUJZ-R2

Overview

The ADR392AUJZ-R2 is a micropower, low noise precision voltage reference with an output of 4.096 V and an initial accuracy of ±6 mV (A grade). It features a temperature coefficient of 25 ppm/°C over the operating range of −40°C to +125°C. The device operates from a supply voltage between 4.3 V and 15 V, drawing a maximum quiescent current of 140 μA. It includes a shutdown feature reducing current to 3 μA and supports up to 5 mA output current without requiring external capacitors.
