低功耗运算放大器和电压比较器 LOW-POWER OPERATIONAL AMPLIFIER AND VOLTAGE COMPARATOR
DESCRIPON/ORDERING INFORMATION
The LM392 consists of two independent building-block circuits. One is a high-gain internally-frequency-compensated operational amplifier, and the other is a precision voltage comparator. Both the operational amplifier and the voltage comparator are designed to operate from a single power supply over a wide range of voltages. Both circuits have input stages that force the common-mode input down to ground when operating from a single power supply. Operation from split power supplies also is possible, and the low power-supply current is independent of the magnitude of the supply voltage.
