Product Information

LM111 LM211 - LM311 VOLTAGE COMPARATORS . . . . . . 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 N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) DESCRIPTION The LM111, LM211 and LM311 are voltage comparators that have low input currents. They are also designed to operateover a wide range of supplyvoltages : from standard ±15V operational amplifier supplies down to the single +5V supply used for IC logic. Their outputis 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.

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 ...
