PRELIMINARY

TYPICAL APPLICATION

The PA86 is ideally suited to driving continuous drop ink jet

systems, in both piezo actuation and deflection applications.

Thedeflectionamplifiershownaboveachievesaccuratedroplet

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.

DESCRIPTION

The PA86 is a high voltage, high speed Precision IC power

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

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

phase. It is important to note that slew rate for the PA86 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

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.
