(1) Typical Values represent the most likely parametric norm.
(2) All limits are guaranteed 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 V
S
= ±15V, V
OUT
=
±5V. For V
S
= +5V, V
OUT
= ±1V.
(4) The open loop output current is the output swing with the 100Ω load resistor divided by that resistor.
