Note 1

This rating applies for g15V supplies The positive input voltage limit is 30V above the negative supply The negative input voltage limit is equal to the

negative supply voltage or 30V below the positive supply whichever is less

Note 2

The maximum junction temperature of the LP311 is 85 C For operating at elevated temperatures devices in the dual-in-line package must be derated

based on a thermal resistance of 160 CW junction to ambient

Note 3

The offset voltage offset current and bias current specifications apply for any supply voltage from a single 4V supply up to g15V supplies

Note 4

The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with 1 mA load Thus these

parameters define an error band and take into account the worst-case effects of voltage gain and input impedance

Note 5

The response time specified is for a 100 mV input step with 5 mV overdrive

Note 6

Saturation voltage specification applies to collector-emitter voltage (V7-1) for VCOLLECTOR s (Va b 3V)

Note 7

This specification gives the range of current which must be drawn from the strobe pin to ensure the output is properly disabled Do not short the strobe pin

to ground It should be current driven 100 mAto300 mA
