Application Circuit
•
•
Bypass capacitors (C1, C2, C3, C4) should be connected as close to the IC as possible.
The Cdp capacitor of 0.01 to 0.1 µF should be connected to channel-F outputs as necessary to prevent the oscillation.
Notes: Excessive power might be introduced into the IC in case of a short-circuit between power supply and ground, an output short-circuit to power supply, an output short-circuit to ground or a short-circuit across the load. If any
of these events occur, the device may be degraded or permanently damaged.
