DESCRIPTION:
The MSK 186 is a dual high power operational amplifier ideal for use with a wide variety of loads. With operation
from either single or dual supplies, it offers excellent design flexibility. Power dissipation is kept to a minimum with a
quiescent current rating of only 26mA per amplifier, while 8 Amps of continuous available output current makes it a
very good low cost choice for motor drive circuits and audio amplification. The design is internally protected against
current overloads and overtemperature conditions. The current limit can also be user-selected through the use of a
resistor/potentiometer or voltage out/current out DAC. The MSK 186 is packaged in a hermetically sealed, isolated 18
pin power DIP with bolt down tabs for applications that require heat sinking.
