RH1011
Voltage Comparator
DESCRIPTION
The RH1011 is a general purpose comparator with signifi-
cantly better input characteristics than the LM111. Al-
though pin compatible with the LM111, it offers four times
lower bias current, six times lower offset voltage and five
times higher voltage gain.
The wafer lots are processed to Linear Technology’s in-
house Class S flow to yield circuits usable in stringent
military applications.

Note 1:
Inputs may be clamped to supplies with diodes so that maximum
input voltage actually exceeds supply voltage by one diode drop. See Input
Protection discussion in the LT
®
1011 data sheet.
Note 2:
T
JMAX
= 150°C.
Note 3:
Output is sinking 1.5mA with V
OUT
= 0V.
Note 4:
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 specication defines a worst-
case error band that includes effects due to common mode signals,
voltage gain and output load.
Note 5:
Drift is calculated by dividing the offset difference measured at
minimum and maximum temperatures by the temperature difference.
Note 6:
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 7:
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 RH1011 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.

See graph, Input Offset Voltage vs Common Mode Voltage on the
LT1011 data sheet.

PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown as the final electrical test in accordance with method
5004 of MIL-STD-883 Class B. The verified failures (including Delta
parameters) of group A, subgroup 1, after burn-in divided by the total
number of devices submitted for burn-in in that lot shall be used to
determine the percent for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
