MP103

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

compensation provides optimum slew rate and insures

stability. The only external components required are

the current limit resistors R

tor R

FEATURES

♦ Low Cost Integrated Solution

♦ Output Current >10A Within SOA

♦ Internal Power Dissipation 35 W Per Channel
