The MSK 103 is an ultra high voltage monolithic MOSFET operational amplifier ideally suited for electrostatic transducer and electrostatic deflection applications. With a total supply voltage rating of 350 volts and 60mA of available output current available from each amplifier, the MSK 103 is also an excellent low cost choice for high voltage piezo drive circuits. The MOSFET output frees the MSK 103 from secondary breakdown limitations and power dissipation is kept to a minimum with a quiescent current rating of only 2mA per amplifier. The MSK 103 is packaged in a hermetically sealed 18 pin ceramic dip which has external compensation pins for each amplifier.
