EQUIVALENT SCHEMATIC

The MSK 155 is a high power dual monolithic operational amplifier ideally suited for high power amplification and

magnetic deflection applications. With a total supply voltage rating of 80 volts and 5A of available output current per

amplifier, the MSK 155 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 MSK 155 is packaged in a hermetically sealed 14 pin power dip with heat

sink bolt down tabs.
