Description
The LMV321/358/324 family (single, dual and quad) answers the need for low-cost, generalpurpose operational amplifiers. They operate with voltages as low as 2.7 V and feature both input and output rail-to-rail, 145 A 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 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 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 k 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 ). 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.
