Description

The PA09 is a high voltage, high output current operational amplifier optimized 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.

High speed and freedom from second breakdown ofPA09 is assured by a complementary Power MOS output stage. For optimum linearity, especially at low levels, the Power MOS transistors are biased in the class A/B mode. Thermal shutoff of PA09 provides full protection against overheating and limits the heatsink requirements to dissipate the internal power losses under normal operating conditions. A built-in current limit protects the amplifier against overloading. Transient inductive load kickback protection is provided by two internal clamping diodes. External phase compensation allows the user maximum flexibility in obtaining the optimum slew rate and gain bandwidth product at all gain settings. For continuous operation under load, a heatsink of proper rating is recommended.

This hybrid integrated circuit utilizes thick film (cermet) resistors, ceramic capacitors and silicon semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires of PA09 provide reliable interconnections at all operating temperatures. The CE, 8-pin TO-3 package of PA09 is hermetically sealed and electrically isolated. The use of com-pressible thermal washers and/or improper mounting torque will void the product warranty. Please see Application Note 1 "General Operating Considerations,"

The PA09A is the A grade version, the PA09M/883 is the certified military grade version.
