Description

The LM111FE, 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 single 3V supply.

Their output is compatible with RTL, DTL, and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50mA.

Applications : 

• Precision squarer

• Positive/negative peak detector

• Low voltage adjustable reference supply

• Switching power amplifier
