Operation from dual power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage. 532/358/LM2904由两个独立的、高增益、低通滤波器组成，内部频率补偿运算放大器内部频率补偿的运算放大器，专门设计用于在宽电压范围内从单个电源操作。双电源操作也是可能的，并且电源电流消耗与电源电压的大小无关。 UNIQUE FEATURES独特的功能 In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage. The unity gain cross frequency is temperature-compensated. The input bias current is also temperature-compensated.在线性模式中，输入共模电压范围包括地，并且输出电压也可以摆动到包括地并且输出电压也可以摆动到地，即使仅从单个电源电压操作。单位收益交叉频率是温度补偿的。输入偏置电流也经过温度补偿。 FEATURES功能 .
