DESCRIPTION
The LMV321, LMV358, and LMV324/LMV324S are
single, dual, and quad low-voltage (2.7 V to 5.5 V)
operational amplifiers with rail-to-rail output swing.
The LMV324S, which is a variation of the standard
LMV324, includes a power-saving shutdown feature
that reduces supply current to a maximum of 5
μA
per channel when the amplifiers are not needed.
Channels 1 and 2 together are put in shutdown, as
are channels 3 and 4. While in shutdown, the outputs
actively are pulled low.
The LMV321, LMV358, LMV324, and LMV324S are
the most cost-effective solutions for applications
where low-voltage operation, space saving, and low
cost are needed. These amplifiers are designed
specifically for low-voltage (2.7 V to 5 V) operation,
with performance specifications meeting or exceeding
the LM358 and LM324 devices that operate from 5 V
to 30 V. Additional features of the LMV3xx devices
are a common-mode input voltage range that
includes ground, 1-MHz unity-gain bandwidth, and 1-
V/μs slew rate.
The LMV321 is available in the ultra-small DCK (SC-
70) package, which is approximately one-half the size
of the DBV (SOT-23) package. This package saves
space on printed circuit boards and enables the
design of small portable electronic devices. It also
allows the designer to place the device closer to the
signal source to reduce noise pickup and increase
signal integrity.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Stresses beyond those listed under
Absolute Maximum Ratings
may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under
Recommended Operating
Conditions
is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values (except differential voltages and V
CC
specified for the measurement of I
OS
) are with respect to the network GND.
Differential voltages are at IN+ with respect to IN–.
Short circuits from outputs to V
CC
can cause excessive heating and eventual destruction.
Maximum power dissipation is a function of T
J

θ

, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is P
D
= (T

. Operating at the absolute maximum T

of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.
