Monolithic MOS Technology
MSK141
MSK142
DESCRIPTION:
The MSK 141 is a high power monolithic MOSFET class 'C' operational amplifier ideally suited for high power
amplification and magnetic deflection applications. With a total supply voltage rating of 150 volts and 5A of available
output current, the MSK 141 is also an excellent low cost choice for motor drive circuits. The MOSFET output frees
the MSK 141 from secondary breakdown limitations and power dissipation is kept to a minimum with a quiescent
current rating of ± 4.0 mA. The MSK 141 is packaged in a hermetically sealed 8 pin power dip and is internally
compensated for gains larger than 10 V/V. For applications requiring heat sinking, the MSK 142 is available with bolt
down tabs and is otherwise identical to the MSK 141 (see mechanical specifications).
