10A Power Amplifier Circuit

Published:2011/7/13 20:16:00 Author:Sue | Keyword: Power, Amplifier | From:SeekIC

The 10A power amplifier uses two high power operational amplifiers OPA541 which can acquire continuous output of 10A. Theupper one is phase reversal amplifier while theunder one is connected with unit gain circuit. For the load, these two amplifiers are output-parallel. The 0.1Ω resistor limits the output current into 5A. The 20pF capacitor is used to prevent high frequency self-excitation.
