TYPICAL APPLICATION CIRCUIT
The PA79 is ideally suited for driving continu-
ous 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 control 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 elec-
trostatic field strength.
