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.
• V
CC
shall use a stable power supply.
(Individual V
CC
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.
