† Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and EMIT OUT grounded.

Full range for LM211Q is −40

°C to 125°C.

‡ All typical values are at TA = 25°C.

NOTES:

7. The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or down to

1 V with a pullup resistor of 7.5 k

Ω to VCC+. These parameters actually define an error band and take into account the worst-case

effects of voltage gain and input impedance.

8. The strobe should not be shorted to ground; it should be current driven at −3 mA to −5 mA (see Figures 13 and 27).

instant when the output crosses 1.4 V.
