GENERAL DESCRIPTION
The MP103 is a high voltage, high output current
dual channel operational ampliier for driving capacitive loads such as piezo devices use in ink jet printing applications. The MP103 utilizes proprietary IC’s
combined with discrete semiconductor and passive
elements on a thermally conductive insulated metal
substrate,deliveringveryhighpowerfromacompact
module. The ampliier gain is ixed at 65 V/V when
thefeedbackpinisconnectedtotheVOUTpin.Internal
compensationprovidesoptimumslewrateandinsures
stability. The only external components required are
thecurrentlimitresistorsRLIM,aseriesisolationresistorRSandthepowersupplybypasscapacitors.

graph).The output stage is protected against transient lyback by the parasitic body diodes of the output stage
