LT1011 Linear Technology, LT1011 Datasheet - Page 3

• Manufacturer Part Number: LT1011
• Description: Voltage Comparator
• Manufacturer: Linear Technology

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
Note 4: Output is sinking 1.5mA with V
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
the low state is I
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 500 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
500 A will strobe the LT1011A if speed is not important. External
leakage on the STROBE pin in excess of 0.2 A when the strobe is “off”
can cause offset voltage shifts.
Note 9: See graph “Input Offset Voltage vs Common Mode Voltage.”
