8. Oscillation stability
Pay due attention on the following points because parasitic oscillation may occur due to effects of the capacity load,
board layout, etc.
(1) Capacity load
When the capacitor is to be inserted between each output pin and GND so as to prevent electric mirror noise, select
the capacitance of maximum 1200pF. (Conditions : Our recommended board, RL = 4)
(2) Board layout
Provide the VCC capacitor of 0.1F in the position nearest to IC.
PREGND must be independently wired and connected to the GND point that is as stable as possible, such as the
minus pin of the 2200
F VCC capacitor.
In case of occurrence of parasitic oscillation, any one of following parts may be added as a countermeasure.
Note that the optimum capacitance must be checked for each set in the mounted state.
Series connection of CR (0.1F and 2.2) between BTL outputs
Series connection of CR (0.1F and 2.2) between each output pin and GND.
