Space Efficient Dual Power Amplifier
Low Cost
High Voltage Operation: Up to 80V
Low Quiescent Current: 40mA Typ. Total
High Output Current: 5A Min. Per Amp
High Speed: 10V/µS Typ.
Monolithic Technology
Replaces obsolete MSK 154 up to 80V
MIL-PRF-38534 QUALIFIED
DESCRIPTION:
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.
