155
DESCRIPTION:
The MSK155 is a high power dual monolithic operational amplifier ideally suited for high power amplification and mag-
netic deflection applications. With a total supply voltage rating of 80 volts and 5A of available output current per amplifier,
the MSK155 is also an excellent low cost choice for motor drive circuits. With both amplifiers in the same package,
thermally induced output offset voltages are eliminated. Power dissipation is kept to a minimum with a total quiescent
current rating of only 40mA. The MSK155 is packaged in a hermetically sealed 14 pin power dip with heat sink bolt down
tabs.
