DESCRIPTION
The PA69 is a high voltage, high speed Precision IC power
A _{op amp with performance and unique features not found previ-}
ously in any commercially available OpAmp .
Novel input stage design of this amplifier provides extremely
IN ^{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 open loop gain and
IM ^{phase. It is important to note that slew rate for the PA69 is}
independent of supply current. However the slew rate is a
strong function of input voltage amplitude. It should be noted
that the package tab needs to be connected to a stable
L 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
E ^{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
R _{gain, stability and bandwidth.}

The PA69 is ideally suited to driving continuous drop ink jet
systems, in both piezo actuation and deflection applications.
The deflection amplifier shown above achieves accurate droplet
displacement at high speeds to deposit crisp, clear lot code
information on product containers. The external compensation
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.
