OPA2830是一款双通道，低功耗，单电源，宽带，电压反馈放大器，采用+ 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1.8V范围内。使用互补的共发射极输出提供输出摆幅，在地面25mV以内，+ V S ，同时驱动150 
高增益带宽积（100MHz）和压摆率确保低失真工作（500V /μs），使OPA2830成为3V和5V CMOS模数转换器（ADC）的理想输入缓冲级。与早期的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9.2nV /
Hz 输入电压噪声支持宽动态范围操作。
OPA2830采用行业标准SO-8封装。 OPA2830还采用小型MSOP-8封装。对于固定增益和线路驱动器应用，请考虑OPA2832。
