LM111-LM211-LM311
Voltage comparator with strobe
Features
■ Maximum input current: 150nA
■ Maximum offset current: 20nA
■ Differential input voltage range: ±30V
■ Power consumption:135mW at ±15V
■ Supply voltage: +5V to ±15V
■ Output current: 50mA
Description
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.

1. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single +5V supply up to
±15V supplies. The offset voltages and offset currents given are the maximum values required to drive the output down to
+1V or up to +14V with a 1mA load current. Thus, these parameters define an error band and take into account the worst-
case of voltage gain and input impedance.
2. The response time specified is for a 100mV input step with 5mV overdrive.
