Protection against mistake in joining.
Terminal protection for short circuit to
+B when VCC terminal is open and
for short circuit to GND when GND
terminal is open.
We recommend Schottky barrier
diodes.
Notes: 1. To improve stability, take notes of the below precautions.
(1) Use capacitor that is temperature independent.
(2) Use capacitor that is bias voltage independent.
(3) No secondary resonance (non-inductive) capacitor.
And, pay attention to the following points so that there can be an efficient bypass of high frequency noise.
(1) To eliminate PCB pattern inductance mount the capacitor as close as possible to the VCC and GND of
IC.
2. For using of the lower limit of recommended value, take notes of the below precautions.
(1) Use capacitor that is temperature independent.
(2) Use capacitor that is bias voltage independent.
(3) No secondary resonance (non-inductive) capacitor.
3. To eliminate PCB pattern inductance mount the capacitor as close as possible to the VCC and GND of IC
about C3, C4, C5, C6 and C7.
The ability to protect
terminal improve.
The ability to protect
terminal lower.
And there is some
possibility of
destruction.
