Ultra-Low-Distortion, +5V,
400MHz Op Amps with Disable
AC ELECTRICAL CHARACTERISTICS (continued)
(VCC = +5V, VEE = 0, RL = 100Ω to VCC/2, VCM = VCC/2, MAX4265/MAX4268 AV = +1V/V, MAX4266/MAX4269 AV = +2V/V,
MAX4267/MAX4270 AV = +5V/V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
