大功率双运算放大器OPA2541是美国BURR-BROWN公司生产的新一代高电压、大电流输出型运算放大器,用于驱动各种电阻性和电抗性负载(如电动机等),并具有较大的安全裕量。利用OPA2541制作的旋转变压器激磁电源,其输出不用升压变压器或谐振电容升压,就能达到旋转变压器的额定激磁电压。一、OPA2541的功能及引脚单片OPA2541功率放大器集成块中有两个单功率放大器,且两个放大器的功能不相等。OPA2541的 High-power dual op amp OPA2541 is the United States BURR-BROWN company produced a new generation of high-voltage, high-current output operational amplifier for driving a variety of resistive and reactive loads (such as motors, etc.), and have a greater safety margin the amount. The use of OPA2541 production of rotary transformer excitation power, the output without step-up transformer or resonant capacitor boost, you can reach the rated voltage of the resolver. First, OPA2541 function and pin monolithic OPA2541 power amplifier block has two single power amplifier, and the two amplifiers do not equal the function. OPA2541’s
