The MP103 is a high voltage, high output current dual channel operational amplifier for driving capacitive loads such as piezo devices used in ink jet printing applications. The MP103 utilizes proprietary ICs 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 65V/V when the feedback pin is connected to the VOUT pin. Internal compensation provides optimum slew rate and insures stability. The only external components required are the current limit resistors RLIM, a series isolation resistor RS and the power supply bypass capacitors.
