DESCRIPTION:
MSK158
MSK159
The MSK 158 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, the MSK 158 is also an excellent low cost choice for high voltage piezo drive circuits. The MOSFET output frees
the MSK 158 from secondary breakdown limitations and power dissipation is kept to a minimum with a quiescent current
rating of only 2mA. The MSK 158 is packaged in a hermetically sealed 8 pin power dip which has two external compensa-
tion pins. For applications requiring heat sinking, the MSK 159 is available with bolt down tabs and is otherwise identical to
the MSK 158 (see mechanical specifications).
