(5)GND voltage
Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state.
Furthermore, check to be sure no terminals are at a potential lower than the GND voltage including an actual electric transient.
(6)Short circuit between terminals and erroneous mounting
In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting can break
down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between terminals or between the terminal
and the power supply or the GND terminal, the ICs can break down.
(7)Operation in strong electromagnetic field
Be noted that using ICs in the strong electromagnetic field can malfunction them.
(8)Inspection with set PCB
On the inspection with the set PCB, if a capacitor is connected to a low-impedance IC terminal, the IC can suffer stress.
Therefore, be sure to discharge from the set PCB by each process. Furthermore, in order to mount or dismount the set PCB
to/from the jig for the inspection process, be sure to turn OFF the power supply and then mount the set PCB to the jig. After the
completion of the inspection, be sure to turn OFF the power supply and then dismount it from the jig. In addition, for protection
against static electricity, establish a ground for the assembly process and pay thorough attention to the transportation and the
storage of the set PCB.
(9)Input terminals
In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the parasitic
element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of the input terminal.
Therefore, pay thorough attention not to handle the input terminals, such as to apply to the input terminals a voltage lower than
the GND respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the input terminals
when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied, apply to the input
terminals a voltage lower than the power supply voltage or within the guaranteed value of electrical characteristics.
(10)Ground wiring pattern
If small-signal GND and large-current GND are provided, It will be recommended to separate the large-current GND pattern
from the small-signal GND pattern and establish a single ground at the reference point of the set PCB so that resistance to the
wiring pattern and voltage fluctuations due to a large current will cause no fluctuations in voltages of the small-signal GND. Pay
attention not to cause fluctuations in the GND wiring pattern of external parts as well.
(11)External capacitor
In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a degradation
in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc.
