General Description
BU7261G,BU7262xxx,BU7264xx are CMOS operational
amplifier of the input/output full swing low voltage
operation. Also, BU7261SG,BU7262Sxxx,BU7264Sxx
which expanded the operating temperature range perform
a lineup. It is most suitable for a sensor amplifier and a
battery-powered equipment to have a high slew rate, the
characteristic of the low input bias current.

Mounted on a FR4 glass epoxy PCB 70mm×70mm×1.6mm (Copper foil area less than 3%).
The voltage difference between inverting input and non-inverting input is the differential input voltage.
Then input pin voltage is set to more than VSS.
(Note 9) An excessive input current will flow when input voltages of more than VDD+0.6V or less than VSS-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.
