EQUIVALENT SCHEMATIC
The MSK 173 is a high power dual operational amplifier. Each amplifier is capable of delivering two amps of
current to the load. The MSK 173 is an excellent low cost alternative for bridge mode configurations since both
amplifiers are packaged together and will track thermally. The wide common mode range includes the negative rail,
facilitating single supply applications. It is possible to have a "ground based" input driving a single supply amplifier
with ground acting as the second or "bottom" supply of the amplifier. The output stage is current limit protected to
approximately 4.0 amps. The MSK 173 is packaged in an extremely space efficient 10 pin power SOIC package. The
MSK 173-1 is packaged in a 10 pin flatpack. Consult the factory for other packaging options if desired.
