LMC7221 Tiny CMOS Comparator with Rail-To-Rail Input and Open Drain Output
September 2006
LMC7221
Tiny CMOS Comparator with Rail-To-Rail Input and Open
Drain Output
General Description
The LM7221 is a micropower CMOS comparator available in
the space saving 5-Pin SOT23 package. This makes this
comparator ideal for space and weight critical designs. The
LMC7221 is also available in the 8-Pin SOIC package. The
LMC7221 is supplied in two offset voltage grades, 5 mV and
15 mV.
The open drain output can be pulled up with a resistor to a
voltage which can be higher or lower than the supply
voltage — this makes the part useful for mixed voltage sys-
tems.
For a tiny comparator with a push-pull output, please see the
LMC7211 datasheet.

Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2:
Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of JEDEC)
Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).
Note 3:
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C. Output currents in excess of
±
30 mA may adversely affect reliability.
Note 4:
The maximum power dissipation is a function of T
J(MAX)
,
θ
JA
. The maximum allowable power dissipation at any ambient temperature is P
D
= (T
J(MAX)
– T
A
)/
θ
JA
. All numbers apply for packages soldered directly onto a PC Board.
Note 5:
Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will
also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material.
Note 6:
All limits are guaranteed by testing or statistical analysis.
Note 7:
Limiting input pin current is only necessary for input voltages which exceed the absolute maximum input voltage rating.
Note 8:
Do not short circuit the output to V
+
when V
+
is greater than 12V or reliability will be adversely affected.
Note 9:
C
L
includes the probe and test jig capacitance.
Note 10:
Input offset voltage average drift is calculated by dividing the accelerated operating life V
OS
drift by the equivalent operational time. This represents worst
case input conditions and includes the first 30 days of drift.
Note 11:
Input step voltage for propagation delay measurement is 2V.
