description/ordering information
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 is a variation of the
standard LMV324 that includes a power-saving
shutdown feature that reduces supply current to a
maximum of 5 µA per channel when the amplifiers
are not needed.
The LMV321, LMV358, LMV324, and LMV324S
are the most cost-effective solutions for
applications where low-voltage operation, space
saving, and low price are needed. These
amplifiers were designed specifically for
low-voltage (2.7 V to 5 V) operation, with
performance specifications meeting or exceeding
the venerable 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 .

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.
NOTES: 1. All voltage values (except differential voltages and VCC specified for the measurement of IOS) are with respect to the network GND.
2. Differential voltages are at IN+ with respect to IN–.
3. Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
4. Maximum power dissipation is a function of TJ(max),
ambient temperature is PD = (TJ(max) – TA)/
5. The package thermal impedance is calculated in accordance with JESD 51-7.
