Note 1:
Stresses beyond those listed under Absolute Maximum Ratings defines a worst-case error band that includes effects due to common may cause permanent damage to the device. Exposure to any Absolute mode signals, voltage gain and output load. Maximum Rating condition for extended periods may affect device
Note 6:
Drift is calculated by dividing the offset voltage difference reliability and lifetime. measured at min and max temperatures by the temperature difference.
Note 2:
Inputs may be clamped to supplies with diodes so that
Note 7:
Response time is measured with a 100mV step and 5mV maximum input voltage actually exceeds supply voltage by one diode overdrive. The output load is a 500Ω resistor tied to 5V. Time drop. See Input Protection in the Applications Information section. measurement is taken when the output crosses 1.4V.
Note 3:
TJMAX = 150°C.
Note 8:
Do not short the STROBE pin to ground. It should be current
Note 4:
Output is sinking 1.5mA with VOUT = 0V. driven at 3mA to 5mA for the shortest strobe time. Currents as low
Note 5:
These specifications apply for all supply voltages from a single as 500µA will strobe the LT1011A if speed is not important. External 5V to ±15V, the entire input voltage range, and for both high and low leakage on the STROBE pin in excess of 0.2µA when the strobe is “off” output states. The high state is I can cause offset voltage shifts. SINK = 100µA, VOUT = (V+ – 1V) and the low state is ISINK = 8mA, VOUT = 0.8V. Therefore, this specification
