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

Notes:
(1)All voltage values, except differential voltage are with respect to network terminal.
(2)The differential voltage is 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 short-circuits
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
SOT23-5 package. The value is given for SO8 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.
