1. Large-signal bandwidth calculated using LSBW = Slew Rate / 2p VPEAK
2. All distortion measurements are made with VOUT = 2VPP, RL = 100W
3. Video performance measured at AV = +2 with 2 times normal video level across RL = 100W. This corresponds to standard video levels across a back-
terminated 50W load, i.e., 0–100 IRE, 40IREpp giving a 1VPP video signal across the 50W load. For other values of RL, see curves
