电压比较器The LM111 series are voltage comparators that have input currents approximately a hundred times lower than devices like the mA710. They are designed to operate over a wider range of supply voltages; from standard ±15V op amp supplies down to a
tional amplifiers concerns operation from a single supply voltage. “Can the model OPAxyz be operated from a single supply?” The answer is almost always yes. Operation of op amps from single supply voltages is useful when negative supply voltages are
