Note) 1. Input offset voltage and indefinite region
Input offset voltage and indefintie region are
existed in the comparator which builds in this IC
as shown right figure. Note that this when
designing external circuit.
2. Pins 22 and 23 for electronic iris mode
Use it in this state of Pin 22 (SPDNV) > Pin 23
(SPUPV).
