NJM2825
Precision Micropower Shunt Voltage Reference
■GENERAL DESCRIPTION
NJM2825 is a precision and low quiescent current shunt voltage
reference.
Reference voltage form bandgap circuit has guaranteed the high
accuracy of the ±0.5% with trimming. In addition the temperature drift of
10ppm/°C typ. was actualized by the temperature compensating circuit.
The reference voltage circuit operates by consumed low quiescent current
of the 0.7µA 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.

Note 1: ⎮VREF⎮···Reference voltage includes error.
Note 2: Reference Voltage Change is defined as
∆VREF_T [mV] = ± < Reference Voltage Change [ppm/°C] > × <-40°C ∼ 25°C> × VREF
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.
