... COUPLED ESD CLAMP GNDC2 V2- CIRCUIT 4B Application Information General The ISL59483 is ideal as the matrix element of high performance switchers and routers. Key features include R L high impedance buffered analog inputs and excellent AC 500: performance at output loads down to 150: for video cable- driving. The current feedback output amplifiers are stable operating into capacitive loads and bandwidth is optimized with a load of 5pF in parallel with a 500: ...
