ANALOG DEVICES ADR4525CRZ Voltage Reference, Series, 2.5 V, 1ppm/°C, 0.02%, 0 °C to 70 °C, NSOIC-8

ADR4525CRZ is a high precision, low power, low noise voltage reference. This voltage reference uses an innovative core topology to achieve high accuracy while offering industry-leading temperature stability and noise performance. The low, thermally induced output voltage hysteresis and low long-term output voltage drift of the device also improve system accuracy over time and temperature variations. A maximum operating current of 950?A and a maximum low dropout voltage of 300mV allow the devices to function very well in portable equipment. Applications include precision data acquisition systems, high resolution data converters, high precision measurement devices, industrial instrumentation, medical devices, automotive battery monitoring.
