OPA4830是一款四通道,低功耗,单电源,宽带,电压反馈放大器,设计采用+ 3V或+ 5V单电源供电。还支持±5V或+ 10V电源供电。输入范围低于负电源,并且在正电源的1.8V范围内。使用互补的共发射极输出可以在驱动150 时提供任意电源220mV以内的输出摆幅。高输出驱动电流(±80mA)和低差分增益和相位误差也使该放大器成为单电源消费类视频产品的绝佳选择。
高增益带宽产品(110MHz)确保低失真工作)和压摆率(560V /μs),使OPA4830成为3V和5V CMOS模数转换器(ADC)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9.2nV / Hz 输入电压噪声支持宽动态范围操作。
OPA4830采用工业标准四引脚排列TSSOP-14封装。
