AC ELECTRICAL CHARACTERISTICS

(VCC = +5V, VEE = -5V, RL = 100Ω, AVCL = +1, TA = +25°C, unless otherwise noted.)

Note 1: Specifications for the MAX477EUK (SOT23 package) are 100% tested at TA = +25°C, and guaranteed by design over

temperature.

Note 2: Maximum AC specifications are guaranteed by sample test on the MAX477ESA only.

Note 3: Tested with a 3.58MHz video test signal with an amplitude of 40IRE superimposed on a linear ramp (0 to 100IRE). An IRE is

a unit of video-signal amplitude developed by the Institute of Radio Engineers. 140IRE = 1V.
