Description
The LMV82x series of single, dual and quad operational amplifiers offers low voltage operation with rail-to-rail output swing. The LMV82x series outperforms the industry standard LMV321 especially with regard to the gain bandwidth product (5.5 MHz). The LMV821, LMV822 and LMV824 are proposed with standard pinouts.

1.All voltage values, except the differential voltage are with respect to the network ground terminal.
2.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3.Vcc-Vin must not exceed 6 V, Vin must not exceed 6 V.
4.The input current must be limited by a resistor in series with the inputs.
5.Vcc-Vshdn must not exceed 6 V, Vin must not exceed 6 V.
6.Short-circuits can cause excessive heating and destructive dissipation.
7.Rth are typical values.
8.Human body model: a 100 pF capacitor is discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of pin combinations while other pins are floating.
9.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 pin combinations while other pins are floating.
10.Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to ground.
