(1)
Typical values represent the most likely parametric norm
 
(2) All limits are specified by testing or statistical analysis.
(3) Large-signal voltage gain is the total output swing divided by the input signal required to produce that swing. For VS = ±15 V,
VOUT = ±5 V. For VS = +5 V, VOUT = ±1 V
(4) The open-loop output current is the output swing with the 100-Ω load resistor divided by that resistor.
(5) Slew rate is the average of the rising and falling slew rates.
(6) Differential gain and phase are measured with AV = +2, VIN = 1 VPP at 3.58 MHz and both input and output 75 Ω terminated.
