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.
