DESCRIPTION:

The MSK 161 is a high output current operational amplifier designed to drive resistive or reactive loads. The Class "C"

output stage is protected by a user programmable current limit scheme. The MSK 161 is designed to be a low cost solution

for low frequency applications where crossover distortion is not critical. The MSK 161 can supply ±10 amps of output

current within its safe operating range and boasts a 16 KHz power bandwidth. A low junction to case thermal resistance of

only 1.2°C/W for the output devices keeps junction temperatures low when driving large load currents.
