ThePA98isahighvoltage, highpowerbandwidthMOSFET  
operationalamplifierdesignedforoutputcurrentsupto200mA.  
Output voltages can swing up to ±215V with a dual supply  
and up to +440 volts with a single supply. The safe operating  
area (SOA) has no second breakdown limitations and can  
be observed with all types of loads by choosing an appropri-  
ate current limiting resistor. High accuracy is achieved with  
a cascode input circuit configuration. All internal biasing is  
referenced to a bootstrapped zener-MOSFET current source.  
Asaresult, thePA98featuresanunprecedentedsupplyrange  
and excellent supply rejection. The MOSFET output stage is  
biasedonforlinearoperation.Externalcompensationprovides  
user flexibility.

DYNAMIC FOCUSING  
Dynamicfocusingistheactivecorrectionoffocusingvoltage  
as a beam traverses the face of a CRT. This is necessary in  
high resolution flat face monitors since the distance between  
cathodeandscreenvariesasthebeammovesfromthecenter  
ofthescreentotheedges.PA98lendsitselfwelltothisfunction  
since it can be connected as a summing amplifier with inputs  
from the nominal focus potential and the dynamic correction.  
The nominal might be derived from a potentiometer, or per-  
haps automatic focusing circuitry might be used to generate  
this potential. The dynamic correction is generated from the  
sweep voltages by calculating the distance of the beam from  
the center of the display.  
Thishybridcircuitutilizesthickfilm(cermet)resistors,ceramic  
capacitors and silicon semiconductor chips to maximize reli-  
ability, minimize size and give top performance. Ultrasonically  
bonded aluminum wires provide reliable interconnections at  
all operating temperatures. The Power SIP package is electri-  
cally isolated.
