DESCRIPTION
The PA44 is a high voltage monolithic MOSFET operational
amplifier achieving performance features previously found
only in hybrid designs while increasing reliability. Inputs are
protected from excessive common mode and differential mode
voltages. The safe operating area (SOA) has no second
breakdown limitations and can be observed with all type loads
by choosing an appropriate current limiting resistor. External
compensation provides the user flexibility in choosing
optimum gain and bandwidth for the application.
The PA44 is packaged in Apex's PSOP1 non-hermetic
surface mountable dual in line package. The metal back of the
package is tied to –Vs.
TYPICAL APPLICATION
The PA44 is set for a gain of 38.5 boosting the 2.33V signal
to 90V. The recommended compensation for gains above 30
is used. If capacitive loading is at least 330pF at all times, the
recommended snubber network may be omitted. The 27 ohm
resistor sets current limit to a nominal value of 111mA to insure
peak currents out of at least 78mA.
