DEFLECTION AMPLIFIER (Figure 1)
The deflection amplifier circuit of Figure 1 achieves arbitrary beam positioning for a fast heads-up display. Maximum transition times are 4µs while delivering 2A pk currents to the 13mH coil. The key to this circuit is the sense resistor (RS) which converts yoke current to voltage for op amp feedback. This negative feedback forces the coil current to stay exactly proportional to the control voltage. The network consisting of RD, RF and CF serves to shift from a current feedback via RS to a direct voltage feedback at high frequencies. This removes the extra phase shift caused by the inductor thus preventing oscillation. See Application Note 5 for details of this and other precision magnetic deflection circuits.
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 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 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 provide reliable interconnections at all operating temperatures. The 8-pin TO-3 +37V di package is hermetically = 15A /µs CC 2pF dt sealed and electrically 3 7 isolated. The use of 4 i = Vi / RS V 8 com-pressible thermal I 1 PA09 washers and/or im5 CF LY proper mounting torque 470pF 13µH 6 will void the product RD 1 warranty.

The specification of PA09A is identical to the specification for PA09 in applicable column to the left. Long term operation at the maximum junction temperature will result in reduced product life. Derate power dissipation to achieve high MTTF. The power supply voltage for all tests is ±35V unless otherwise specified as a test condition. +VS and -VS denote the positive and negative supply rail respectively. Total VS is measured from +VS to VS. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz. The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes.
