Application Circuit Block Diagram
Notes for Power-on
Of the four –7.0V, +15.0V, +3.3V, +5.0V power supplies, be sure to start up the –7.0V and +15.0V power
supplies in the following order to prevent the SUB pin of the CCD image sensor from going to negative
potential.
This block diagram shows the connection relationship with each block, and is not an actual circuit diagram.
See the CCD image sensor data sheet for a concrete example of circuit connection with a CCD image sensor.
Application circuits shown are typical examples illustrating the operation of the devices. Sony cannot assume responsibility for
any problems arising out of the use of these circuits or for any infringement of third party patent and other right due to same.
