Mounted on an FR4 glass epoxy PCB 70mm×70mm×1.6mm (Copper foil area less than 3%).
Differential Input Voltage is the voltage difference between the inverting and non-inverting inputs.
The input pin voltage is set to more than V
SS
.
(Note 10) An excessive input current will flow when input voltages of more than V
DD
+0.6V or less than V
SS
-0.6V are applied.
The input current can be set to less than the rated current by adding a limiting resistor.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
