(1) Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of V+.
The normal operation will establish when any input is within the Common Mode Input Voltage Range of electrical characteristics.
(2) Differential voltage is the voltage difference between +INPUT and -INPUT.
(3) Excessive input current will flow if a differential input voltage in excess of approximately 0.5 V is applied between the inputs,
unless some limiting resistance is used.
(4) The output may be shorted to ground or either power supply. Temperature and/or supply voltages must be limited to ensure the maximum dissipation rating
is not exceeded.

■ APPLICATION INFORMATION
• Back-to-back Diode Protection
The input terminals of the NJM5532C are protected from excessive differential voltage by back-to-back diodes.
However, When used in voltage follower circuit, the back-to-back diode may break at power on.
Therefore, put a current-limiting resistance to input terminal as shown Fig.1.

• Caution to Thermal Design
If the NJM5532C junction temperature (Tj) exceeds guaranteed
value (150 degree) and the package power dissipation (PD),
there is possibility of the NJM5532C deterioration or breakdown.
The NJM5532C supply current is higher (ICCMAX=16mA at V+/V-
=±15V,Ta=+25˚C) and has positive temperature coefficient
(Refer to Supply Current vs. Temperature characteristic).
Therefore, you should carefully design with due attention to the
supply voltage, the internal power dissipation and the ambient
temperature.
