DEFLECTIONꢀAMPLIFIERꢀ(Figure 1)  
The deflection amplifier circuit of Figure 1 achieves arbi-  
trary 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 (R )  
which converts yoke current to voltage for op amp feedbacSk.  
This negative feedback forces the coil current to stay exactly  
proportional to the control voltage. The network consisting of  
R , RF and CF serves to shift from a current feedback via RS  
toDa 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  
thevideofrequencyrange.Excellentinputaccuracyisachieved  
with a dual monolithic FET input transistor which is cascoded  
bytwohighvoltagetransistorstoprovideoutstandingcommon  
modecharacteristics.Allinternalcurrentandvoltagelevelsare  
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.

Highspeedandfreedomfromsecondbreakdownisassured  
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  
normaloperatingconditions.Abuilt-incurrentlimitprotectsthe  
amplifieragainstoverloading.Transientinductiveloadkickback  
protectionisprovidedbytwointernalclampingdiodes.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.
