Test Circuit for Frequency Response

( 1) It is recommended that a by-pass capacitor of more than 0.01

µF be added between V

CC

and

GND near the device in order to stabilize power supply line.

( 2) Transistor of detector side in bipolar configuration is apt to be affected by static electricity

for its minute design. When handling them, general counterplan against static electricity

should be taken to avoid breakdown of devices or degradation of characteristics.

s Precautions for Use

( 3) As for other general cautions, refer to the chapter “ Precautions for Use ”
