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.
