Proper Cares in Using IC
1. Maximum ratings
Extreme caution should be excrcised when using the IC in the vicinity of the maximum ratings as a slight factor may
cause the maximum ratings to be exceeded, thereby leading to a breakdown accident.
2. Pin-to-pin short
If the power supply is truned ON with pin-to-pin short, a breakdown or de-gradation may occur. When installing the IC
on the board, be sure to check that pin-to-pin area is not shorted with solder, etc. and turn ON the power supply.
3. Printed Circuit Board
When designing the printed circuit board, make the power supply and ground lines thicker and shorter so that no
feedback loop of input/output is formed. When using under the condition where the signal source impedance (Rg) is
large, a stable operation against distortion is obtained by separating the input /output ground line at the root of GND pin
[pin (8)]. The heat sink fin must be reliably connected to the external line of the same potential as pin (8) (GND).
