CA3224E Overview
The CA3224E is an automatic picture tube bias control circuit used in color TV receiver CRT drive circuits. It is used to provide dynamic bias control of the grey scale both initially and over the CRT operating life, pensating for CRT cutoff changes. The CA3224E provides automatic continuous control of the cutoff current in each gun of a three-gun color CRT.
