Novelinputstagedesignofthisamplifierprovidesextremely  
high slew rates in pulse applications while maintaining low  
quiescent current of under 1mA. This novel input stage also  
has the effect of adding variables to the power response and  
slew rate characteristics of the amplifier. To a lesser degree,  
there are also input related effects on unity gain bandwidth  
and phase. It is important to note that the slew rate is a strong  
functionofinputvoltageamplitude.Itshouldbenotedthatthe  
package tab needs to be connected to a stable reference  
such as GND for high slew rates. Please refer to special  
considerations section for details.  
The output stages are well protected with user defined  
current limit although the Safe Operating Area (SOA) must  
be observed for reliable protection. Proper heatsinking is  
required for maintaining maximum reliability. External phase  
compensation provides the user with great flexibility in trading  
gain, stability and bandwidth.

The PA86 is ideally suited to driving continuous drop ink jet  
systems, in both piezo actuation and deflection applications.

networks have been optimized to match the gain of the circuit  
and the complex impedance of the load. The combination of  
high voltage and high speed allow repeatable low cost deflec-  
tion of droplets for high production environments.
