Sample Application Circuit : Camera Block Diagram
Proper Cares to be Taken in Designing a Printed Circuit Board
The LB8901M draws a large instantaneous current when it drives a load. The LB8901M is also designed to drive a load at
a very high speed. When designing a printed circuit board, keep in mind the following points to prevent the output wave-
forms from being adversely affected.
1) Make the pattern of the power supply, GND lines as large as possible.
2) Place the bypass capacitor as close to the IC as possible (less than 1cm).
3) Make the wiring of the input signal line as short as possible to minimize the effect of stray capacitance.
4) Make the wiring of the output signal line also as short as possible, because the inductance of a long signal line may affect
the output waveforms adversely.
Take such necessary measures that a small resistance is inserted in series with a load.
5) When using a power save circuit, place it also as close to the IC as possible.
