OPA832是一款低功耗,高速,固定增益放大器,采用+ 3.3V或+ 5V单电源供电。还支持±5V或+ 10V电源供电。输入范围延伸到地电压以下,并且在正电源的1V范围内。使用互补的共发射极输出可提供低于地电压30mV和正电源130mV的输出摆幅。高输出驱动电流和低差分增益和相位误差也使其成为单电源消费类视频产品的理想选择。
高增益带宽积(200MHz)和压摆率(850V)确保低失真工作/μs),使OPA832成为3V和5V CMOS转换器的理想输入缓冲级。与其他低功耗,单电源放大器不同,失真性能随着信号摆幅的降低而提高。低9.3nV / Hz 输入电压噪声支持宽动态范围操作。
OPA832采用行业标准SO-8封装。 OPA832还采用超小型SOT23-5封装。对于+1,?? 1或+2以外的增益,请考虑使用OPA830。
