●CAUTIONS ON USE
1) Absolute Maximum Ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions,
etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open
circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given
to take physical safety measures including the use of fuses, etc.
2) GND voltage
Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating
state.
3) Thermal design
Perform thermal design in which there are adequate margins by taking into account the permissible dissipation
(Pd) in actual states of use.
4) Pin short and mistake fitting
When mounting the IC on the PCB, pay attention to the orientation of the IC. If there is a placement mistake, the
IC may be burned up.
5) Operation in strong electric field
Be noted that using ICs in the strong electric field can malfunction them.
6) Mutual impedance
Use short and wide wiring tracks for the power supply and ground to keep the mutual impedance
as small as possible. Use a capacitor to keep ripple to a minimum.
7) 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.
