KA7305

KA7305 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. B/W CCD PROCESSOR 48-QFP-0707 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.
