Caution 1: 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.
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with power dissipation taken into consideration by increasing
board size and copper area so as not to exceed the maximum junction temperature rating.
(Note 2) To use at temperature above Ta=25 C reduce 7.0 mW/°C.
(Note 3) Mounted on an FR4 glass epoxy PCB 70 mm×70 mm×1.6 mm (Copper foil area less than 3 %).
(Note 4) The differential input voltage indicates the voltage difference between inverting input and non-inverting input.
The input pin voltage is set to more than VSS.

(Note 7) Consider the power dissipation of the IC under high temperature environment when selecting the output current value.
When the output pins are short-circuited continuously, the output current may decrease due to the temperature rise by the heat generation of inside the
IC.
