1. Slew rate is measured on rising edge.
2. For VS = ±15V, VOUT = 20VPP. For VS = ±5V, VOUT = 5VPP. Full-power bandwidth is based on slew rate measurement using: FPBW = SR/(2p *
Vpeak).
3. Video Performance measured at VS = ±15V, AV = +2 with 2 times normal video level across RL = 150W. This corresponds to standard video levels
across a back-terminated 75W load. For other values of RL, see curves.
