(When GND is the output, the input polarity is reversed.) (When GND is the output, the input polarity is reversed.) High flexibility voltage comparator Summary LM311DR and LM211DR can work on a single power supply of 5V to 30V or a dual power supply of ±15V. Like the commonly used comparator, LM311 can become a real universal comparator. The input ofLM311DR and LM211DR can be isolated from the system, and the output can be referenced to ground, power supply or VEE. This flexibility can drive DTL, RTL, TTL or MOS level logic. When the output current is 50MA, the output can switch the voltage to 50V, which can be used to drive relays, lamps or solenoids.

NOTES: 1. The specifications of offset voltage, offset current and bias current correspond to the power supply voltage of 5V to ±15V. 2. This rating is for the case of ±15V power supply. The positive input voltage limit is 30V higher than the negative power supply, and the negative input limit is equivalent to the negative power supply voltage, or 30V lower than the power supply, or whichever is smaller. 3. Given offset voltage and offset current, it is required to drive a load with a maximum value of 1mA in any power supply voltage range, and these parameters define the error range, thus taking the worst case of voltage gain and input impedance into account. 4. The specified response time is 100Mv input plus 5MV overdrive signal. 5. Don't directly ground the STROBE pin, it needs to be driven by 3mA~5mA current. www.umw-ic.com 3 UTD Semiconductor Co.,Limited High flexibility voltage comparator UMW LM311 LM211 R
