MSK181Z

MSK181

DESCRIPTION:

The MSK 181 is a high power monolithic operational amplifier ideal for use with a wide variety of loads. With operation from

either single or dual supplies, the MSK 181 offers excellent design flexibility. Power dissipation is kept to a minimum with a

quiescent current rating of only 20mA, while 3 Amps of continuous available output current makes the MSK 181 a very good low

cost choice for motor drive circuits and audio amplification. The MSK 181 is internally protected against current overloads and

overtemperature conditions. Current limit can also be user-selected through the use of a resistor/potentiometer or voltage out/

current out DAC. The MSK 181 is packaged in a hermetically sealed 8 pin power dip and the MSK 181Z is offered with bolt down

tabs for applications that require heat sinking.
