GENERAL DESCRIPTION
The MP103 is a high voltage, high output current
dual channel operational amplifier for driving capaci-
tive loads such as piezo devices use in ink jet print-
ing applications. The MP103 utilizes proprietary IC’s
combined with discrete semiconductor and passive
elements on a thermally conductive insulated metal
substrate, delivering very high power from a compact
module. The amplifier gain is fixed at 65 V/V when
the feedback pin is connected to the V_OUT pin. Internal
compensation provides optimum slew rate and insures
stability. The only external components required are
the current limit resistors R_LIM, a series isolation resis-
tor R_S and the power supply bypass capacitors.
