LMC7211 Tiny CMOS Comparator with Rail-to-Rail Input and Push-Pull Output
September 1999
LMC7211
Tiny CMOS Comparator with Rail-to-Rail Input and
Push-Pull Output
General Description
The LMC7211 is a micropower CMOS comparator available
in the space saving SOT23-5 package. This makes the com-
parator ideal for space and weight critical designs. The
LMC7211 is supplied in two offset voltage grades, 5 mV and
15 mV.
The main benefits of the Tiny package are most apparent in
small portable electronic devices, such as mobile phones,
pagers, notebook computers, personal digital assistants,
and PCMCIA cards. The rail-to-rail input voltage makes the
LMC7211 a good choice for sensor interfacing, such as light
detector circuits, optical and magnetic sensors, and alarm
and status circuits.
The Tiny Comparator’s outside dimensions (length x width x
height) of 3.05mm x 3.00mm x 1.43mm allow it to fit into tight
spaces on PC boards.

Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended 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, 1.5 kΩ in series with 100 pF.
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 over long term may adversely affect reliability.
Note 4:
The maximum power dissipation is a function of T
J(max)
,
θ
JA
, and T
A
. 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 into a PC board.
Note 5:
Typical values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.
Note 7:
Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage rating.
Note 8:
Do not short circuit output to V+, when V+ is greater than 12V or reliability will be adversely affected.
Note 9:
C
L
includes the probe and 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.
