DESCRIPTION

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.

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 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.

tors, ceramic capacitors and silicon semiconductor chips to

maximize reliability, minimize size and give top performance.

Ultrasonically bonded aluminum wires provide reliable inter-

connections at all operating temperatures. The CE, 8-pin TO-3

package is hermeti-

cally sealed and elec-

trically isolated. The

use of com-pressible

thermal washers and/

or improper mount-

ing torque will void

the product warranty.
