USE WITH PRECAUTIONS

 Power Supply (Dual Power Supply / Single Power Supply)

The op amp operates when a predetermine voltage is applied between V + - V – . Therefore, while it operates

from a single power supply (V - = GND), it is not possible to operate the input and output near GND. So

please be careful of the common-mode input voltage range and maximum output voltage.

 Ratings of input/output pin voltage

When the voltage of input/output pin exceeds the absolute maximum rating, the parasitic diode within the

IC may conduct, causing characteristics degradation or damage. In addition, if the input pin is lower than

V−, or the output pin exceeds the power supply voltage, it is recommended to make a clamping circuit using

a diode with low forward voltage (e.g.: Schottky diode) as protection.

 Range of common-mode input voltage

When the supply voltage does not meet the condition of electrical characteristics, the range of common-

mode input voltage is as follows.

VICM (TYP.) : V - +3 ~ V + -1 [V] (TA = 25

C)

During designing, do include some margin by considering characteristics variation, temperature

characteristics etc.

 Maximum Output Voltage

The TYP. value range of the maximum output voltage when the supply voltage does not meet the condition

of electrical characteristics is as follows:

Vom + (TYP.) : V + -1 [V] (TA = 25

C), Vom - (TYP.) : V - +1.7 [V] (TA = 25 C)

During designing, do include some margin by considering characteristics variation, temperature

characteristics and so on. In addition, also note that the output voltage range (Vom+ − Vom−) will become

narrow when the output current increases.

 Handling of ICs

When stress is added to the ICs due to warpage or bending of a board, the characteristic may fluctuates

due to piezoelectric (piezo) effect. Therefore, pay attention to warpage or bending of a board.
