USE WITH PRECAUTIONS

• Set Current (ISET)

This IC is a circuit configuration that supplies current to each internal element by flowing a set current (ISET) (the direction

in which it flows out of the IC). Be sure to apply the set current when using. Also, make sure that the potential of the

ISET pin does not exceed the range of V - ~ V +.

• Power Supply (Dual Power Supply / Single Power Supply)

The op-amp operates as long as a predetermined voltage is applied between V + and V -.

Therefore, it can operate with a single power supply (V - = GND), but it cannot operate the input and output near GND.

Common-mode input voltage Please pay attention to the 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 - +0.4 ~ V + -0.7 [V] (TA = 25 °C)

During designing, do include some tolerance by considering 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 [V] (TA = 25 °C)

During designing, do include some tolerance 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 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.
