ELECTRICAL CHARACTERISTICS
The q denotes the specifications which apply over the full operating temperature range, otherwide specifications are at T_A = 25°C.
V_S = ±15V, V_CM = 0V, R_S = 0Ω, V₁ = –15V, output at pin 7 unless otherwise noted.

*Indicates parameters which are guaranteed for all supply voltages, including a single 5V supply. See Note 5.
Note 1: Absolute Maximum Ratings are those values beyond which the
life of a device may be impaired.
Note 2: Inputs may be clamped to supplies with diodes so that
maximum input voltage actually exceeds supply voltage by one diode
drop. See Input Protection in the Applications Information section.
Note 3: T_JMAX = 150°C.
Note 4: Output is sinking 1.5mA with V_OUT = 0V.
Note 5: These specifications apply for all supply voltages from a single
5V to ±15V, the entire input voltage range, and for both high and low
output states. The high state is I_SINK ≥ 100µA, V_OUT ≥ (V⁺ – 1V) and
the low state is I_SINK ≤ 8mA, V_OUT ≤ 0.8V. Therefore, this specification
defines a worst-case error band that includes effects due to common
mode signals, voltage gain and output load.
Note 6: Drift is calculated by dividing the offset voltage difference
measured at min and max temperatures by the temperature difference.
Note 7: Response time is measured with a 100mV step and 5mV
overdrive. The output load is a 500Ω resistor tied to 5V. Time
measurement is taken when the output crosses 1.4V.
Note 8: Do not short the STROBE pin to ground. It should be current
driven at 3mA to 5mA for the shortest strobe time. Currents as low as
500µA will strobe the LT1011A if speed is not important. External
leakage on the STROBE pin in excess of 0.2µA when the strobe is “off”
can cause offset voltage shifts.
Note 9: See graph “Input Offset Voltage vs Common Mode Voltage.”
