NJM2823 Precision Micropower Shunt Voltage Reference GENERAL DESCRIPTION PACKAGE OUTLINE NJM2823 is a precision and low quiescent current shunt voltage reference. Reference voltage form bandgap circuit has guaranteed the high accuracy of the 0.4% with trimming. In addition the temperature drift of 15ppm/C typ. was actualized by the temperature compensating circuit. NJM2823F The reference voltage circuit operates by consumed low quiescent current of the 60 A for low power technology. The Output capacitor is unnecessary by the phase compensating circuit which is built in. Tolerates capacitive loads, it is easy to use for application. It is suitable for data converters, instrumentation, and other applications where precision reference is required.

The maximum value of Reference Voltage Change is determined based on sampling evaluation from the 5 initial production lots, and thus not tested in the production test. Therefore, these values are for the reference design purpose only. (*1): Test Circuit (Fig.1) (*2): Test Circuit (Fig.2) Ver.2009-03-05 - 2 -
