EQUIVALENT SCHEMATIC
The MSK 171/172 is a high power dual operational amplifier. Each amplifier is capable of delivering three amps of
current to the load. The MSK 171/172 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. To maintain stability, output snubber networks
have been internally connected to each op amp output (see "amplifier stability" in the attached application notes).
The output stage is also current limit protected to approximately 3.0 amps. The MSK 171 is packaged in a space
efficient 8-pin power dip while the MSK 172 is packaged in an 8-pin z-pack power dip with heat sink attach tabs.
Consult factory for other packaging options if desired.
