DESCRIPTION
The PA17 is a high voltage MOSFET power operational
amplifier that extends the performance limits of power ampli-
fiers in slew rate and power bandwidth, while maintaining high
current and power dissipation ratings.
The PA17 is a highly flexible amplifier. The shutdown
feature allows ultra-low quiescent current for standby opera-
tion or load protection by disabling the entire amplifier. Boost
voltage inputs allow the small signal portion of the amplifier to
operate at a higher voltage than the high current output stage.
The amplifier is then biased to achieve close linear swings to
the supply rails at high currents for extra efficient operation.
External compensation tailors performance to user needs. A
four wire sense technique allows current limiting without the
need to consider internal or external milliohm parasitic resis-
tance in the output line.
