ELECTRICAL CHARACTERISTICS
ELECTRICAL CHARACTERISTICS TEST METHOD
Note: SW/NO of signal input pin and SW/NO of pulse input pin,
which have already been described in the electrical characteristics
table, are omitted, and SW/NO of external power supply will only be
described as follows:
Sub-OSD adjustment voltages, V32, V27 and V22, which are
always set to the identical value, are represented by V32 in the
electrical characteristics table. In addition, sub-contrast voltages,
V4, V9 and V14, which are also set to the identical value, are
represented by V4 in the electrical characteristics table.
Icc circuit current
Conditions shall be as specified in the electrical characteristics
table, and take measurements with ammeter A when SWA is turned
to the b side.
Vomax output dynamic range
Follow the following procedure to set V19.
1. Input SG5 to pin
2. Then, gradually raise V19, and read the upper part voltage when
