The LMV321/358/324 family (single, dual and
quad) answers the need for low cost, general
purpose operational amplifiers. They operate with
voltages as low as 2.7 V and feature both input
and output rail-to-rail, 145 µA consumption
current and 1 MHz gain bandwidth product
(GBP).

(SO-14, TSSOP-14)
With a such low consumption and a sufficient
GBP for many applications, these op-amps are
very well-suited for any kind of battery-supplied
and portable equipment application.
The LMV321 is housed in the space-saving 5-pin
SOT23-5 package which simplifies the board
design (overall dimensions are 2.8 mm x 2.9 mm).
The SOT23-5 has two pinning configurations to
answer all application requirements.

1. All voltage values, except differential voltage are with respect to network terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If
Vid > ±1 V, the maximum input current must not exceed ±1 mA. In this case (Vid > ±1 V), an input series
resistor must be added to limit input current.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers. All values are typical.
4. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
5. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
6. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
No value specified for CDM on SOT23-5L package. The value is given for SO and TSSOP packages.
7. Short-circuits from the output to VCC can cause excessive heating. The maximum output current is
approximately 48 mA, independent of the magnitude of VCC. Destructive dissipation can result from
simultaneous short-circuits on all amplifiers.

Package information
In order to meet environmental requirements, STMicroelectronics offers these devices in
ECOPACK® packages. These packages have a lead-free second level interconnect. The
category of second level interconnect is marked on the package and on the inner box label,
in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an STMicroelectronics
trademark. ECOPACK specifications are available at: www.st.com.
