Note 5: These parameters, although ensured over the recommended operating conditions, are not 100% tested in production.

Note 7: DC transconductance (gM) relates to DC open-loop voltage gain (AV) according to the following equation: AV =gMRL
where RL is the resistance from pin 9 to ground. The minimum gM specification is used to calculate minimum AV when the
error amplifier output is loaded.
