Power amplifying integrated circuit PA09

operationalhybridisolated

The PA09 is a 5A, 80V power operational amplifier designed to drive a variety of loads from DC through the video frequency range. Excellent input accuracy is achieved with a dual monolithic FET input transistor which is cascoded by two high voltage transistors to provide outstanding common mode characteristics. All internal current and voltage levels are referenced to a zener diode biased on by a current source. As a result, the PA09 exhibits superior DC and AC stability over a wide supply and temperature range. A high 200V/µs slew rate and freedom from second breakdown is assured by a complementary Power MOS output stage. Thermal shutoff provides full protection against overheating and limits heat sinking requirements to dissipate the internal power losses under normal operating conditions. A built-in current limit protects the amplifier against overloading. External phase compensation allows the user maximum flexibility in obtaining optimum slew rate and gain bandwidth product at all gain settings. PA09A is the A grade version providing enhance performance in the areas of offset voltage, offset current and bias current. The PA09M/883 is the fully certified military grade version. The PA09 series is a hybrid product design housed in an electrically isolated, hermetically sealed 8-pin TO-3 metal package. For continuous operation under load, a heatsink of proper rating is recommended.
