(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 V
S
= ±15V, V
OUT
=
±5V. For V
S
= ±5V, V
OUT
= ±1V.
(4) The open loop output current is specified, by the measurement of the open loop output voltage swing, using 100Ω output load.
