The LM111, LM211, LM311 are voltage comparators that have low input currents.
They are also designed to operate over a wide range of supply voltages: from standard ±15V operational amplifier supplies down to the single +5V supply used for IC logic.
Their output is compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +50V at output currents as high as 50mA.Key Features
- Output current: 50mA
- Maximum input current: 150nA
- Differential input voltage range: ±30V
- Maximum offset current: 20nA
- Supply voltage: +5V to ±15V
- Power consumption:135mW at ±15V
