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.

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.

a 1.5 kW 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 W). This is done for all couples

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.
