Cautions for Manufacturing Boards

Built-in wide band preamplifier may cause oscillation due to the wiring shape on the board.

Be careful for the following points.

• VCC shall use a stable power supply.

(Individual VCC should use an independent power supply.)

• GND should be as wide as possible. Basically, solid earth should be used.

Make the load capacitance of output pins as small as possible.

• Also ground the hold capacitance to stable GND, which is as near to the pin as possible.

• Insertion of a resistance of several tens of ohms between the output pin and the circuit at the next stage makes

oscillation harder.

• When inserting an output pull-down resistance, make wire between the output pin and the resistance as short as

possible.
