○Application example

(1) Absolute maximum ratings

Absolute maximum ratings are the values which indicate the limits,

within which the given voltage range can be safely charged to the terminal.

However, it does not guarantee the circuit operation.

(2) Applied voltage to the input terminal

For normal circuit operation of operational amplifier, please input

voltage for its

input terminal within input common mode voltage VDD+0.3[V].

Then, regardless of power supply voltage,VSS-0.3[V] can be applied to input

terminals without deterioration or destruction of its characteristics.

(3) Operating power supply (split power supply/single power supply)

The operational amplifier operates if a given level of voltage is applied between VDD and

VSS. Therefore, the operational amplifier can be operated under single power supply

or split power supply.

(4) Power dissipation (pd)

If the IC is used under excessive power dissipation. An increase in the chip temperature will cause

deterioration of the radical characteristics of IC.

For example, reduction of current capability. Take consideration of the effective power dissipation and

thermal design with a sufficient margin. Pd is reference to the provided power dissipation curve.

(5) Short circuits between pins and incorrect mounting

Short circuits between pins and incorrect mounting when mounting the IC on a printed circuits board,

take notice of the direction and positioning of the IC.

If IC is mounted erroneously, It may be damaged. Also, when a foreign object is inserted between

output, between output and VDD terminal or VSS terminal which causes short circuit, the IC may be damaged.
