PRECAUTIONS FOR USE
O The process of unused circuits
If there is an unused circuit, the following connection is recommended.

To potentials within the range of
common-mode input voltage (V

Remark
A midpoint potential of V

and V
is applied to this example.
O Ratings of input/output pin voltage
When the voltage of input/output pin exceeds the absolute maximum rating, it may cause degradation of
characteristics or damages, by a conduction of a parasitic diode within an IC. In addition, when the input pin may be
lower than V
, or the output pin may exceed the power supply voltage, it is recommended to make a clump circuit by
a diode whose forward voltage is low (e.g.: Schottky diode) for protection.
O 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.

O The maximum output voltage
The range of the TYP. value of the maximum output voltage when the supply voltage does not meet the condition
of electrical characteristics is as follows:

During designing, consider variations in characteristics and temperature characteristics for use with allowance.
In addition, also note that the output voltage range (V

) becomes narrow when an output current
increases.
O Operation of output
This IC consist an output level of a class C push-pull. Therefore, when a load resistance is connected to the
midpoint potential of V
+
, V
, a crossover distortion occurs at the transition state of output current flow direction
(source, sink).
O Handling of ICs
When stress is added to ICs due to warpage or bending of a board, the characteristic fluctuates due to
piezoelectric effect. Therefore, pay attention to warpage or bending of a board.
