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/(2π *

Vpeak).

3. Video Performance measured at VS = ±15V, AV = +2 with 2 times normal video level across RL = 150Ω. This corresponds to standard video levels

across a back-terminated 75

Ω load. For other values of RL, see curves.
