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
≥
100
μ
A, V
OUT
≥
(V
+
– 1V) and
the low state is I
SINK
≤

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 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
μ
A will strobe the LT1011A if speed is not important. External
leakage on the STROBE pin in excess of 0.2
μ
A when the strobe is “off”
can cause offset voltage shifts.
Note 9:
See graph “Input Offset Voltage vs Common Mode Voltage.”
*
Indicates parameters which are guaranteed for all supply voltages, including a single 5V supply. See Note 5.
