LM311N

LM211, LM311 Voltage comparator with strobe Datasheet - production data Description The LM211, LM311 are voltage comparators that have low input currents. D SO-8 (Plastic micropackage) They are also designed to operate over a wide range of supply voltages: from standard ±15 V operational amplifier supplies down to the single +5 V supply used for IC logic. Pin connections (top view) Their output is compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +50 V at output currents as high as 50 mA. Features • Maximum input current: 150 nA • Maximum offset current: 20 nA • Differential input voltage range: ±30 V • Power consumption:135 mW at ±15 V • Supply voltage: +5 V to ±15 V • Output current: 50 mA Table 1.

This rating applies for ±15V supplies. The positive input voltage limit is 30V above the negative. The negative input voltage is equal to the negative supply voltage or 30V below the positive supply, whichever is less. 2. Pd is calculated with Tamb = +25°C, Tj = +150°C and Rthja = 175°C/W for the SO-8 package. Table 3.

The offset voltage, offset current and bias current specifications apply for any supply voltage from a single +5 V supply up to ±15 V supplies. The offset voltages and offset currents given are the maximum values required to drive the output down to +1 V or up to +14 V with a 1 mA 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 100 mV input step with 5 mV overdrive.
