Description

The LMV321L, LMV358L and LMV324L are single, dual and quad operational amplifiers with rail-to-rail output capabilities. They are specifically designed to operate at low voltages (2.7 to 5 V) with enhanced performances compared to the industry standard LM3xx series.

The LMV321L, LMV358L and LMV324L are offered in tiny packages, allowing the devices to be used in small portable electronic applications and be placed closer to the actual signal.

The LMV321L, LMV358L and LMV324L are complete cost-effective solutions for designs where cost is of primary importance.

1.All voltage values, except differential voltage, are with respect to 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.Input current must be limited by a resistor in series with the inputs.

5.Short-circuits can cause excessive heating and destructive dissipation.

6.Rth are typical values.

7.Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating.

8.Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.

9.Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
