Note) Each item is evaluated by Measurement Circuit.
Notes on Operation (See Application Circuit.)
1. Be sure to protect against static electricity because this IC is MOS structure.
2. A bypass capacitor (0.1µF or more) is connected between GND and near each power supply (VH, VDD, VL).
3. In order to protect CCD image sensor, input SHT pin output to SUB pin of CCD image sensor after that has been clamped at VH.
