NOTES: 1. Unless otherwise noted: TC = 25°C, DC input specifications are ± value given, power supply voltage

is typical rating.

2. Long term operation at the maximum junction temperature will result in reduced product life. Derate

power dissipation to achieve high MTTF.

3. +VS and –VS denote the positive and negative supply voltages of the output stage.

4. Rating applies if output current alternates between both output transistors at a rate faster than 60Hz.

5. Supply current increases with signal frequency. See graph on page 4.

Typical AppLICATION Circuit

The PA86 is ideally suited for driving continuous drop

ink jet printers, in both piezo actuation and deflection

applications. The high voltage of the amplifier creates

an electrostatic field on the deflection plates to con-

trol the position of the ink droplets. The rate at which

droplets can be printed is directly related to the rate

at which the amplifier can drive the plate to a different

electrostatic field strength.
