KA7305
B/W CCD PROCESSOR
GENERAL DESCRIPTION
The KA7305 is a monolithic integrated circuit for B/W CCD
camera 1 chip signal processor.
It contains functional block from CDS to video driver and
2 comparators for EE mode. Also, it performs a low power
onsumption and a small dimension of set implementation
by decreasing external parts as a 1 chip.
FEATURES
* 5 Steps sample & hold.
* 4 dB ~ 32 dB AGC gain control.
* Built in 2 comparators for EE mode control.
* EE mode WND / BLK selectable.
* Gamma γ = 0.45 / Linear output separation.
* Built in OP-AMP for AGC loop.
* 3 Mode set-up control.
* 2 Mode white / clip control.
* 75 Ohm video driver & sag compensation.
