DescriptionThe LMX3xx series is a set of single, dual, and
quad low-voltage, general-purpose, operational
amplifiers. These devices can operate from 2.3 V
to 5.5 V with a typical current consumption of
120 μA per channel. The LMX3xx series offers a
rail-to-rail output and an input common-mode
voltage that includes ground.
The LMX3xx series also exhibits a 1.3 MHz gain
bandwidth and they can drive capacitive loads.
The devices are stable while operating at unity
gain. They are offered with industry standard
pinouts in tiny packages.

Absolute maximum ratings and operating conditions LMX321, LMX358, LMX324
4/25 DocID022943 Rev 3 Absolute maximum ratings and operating conditions
Table 2. Absolute maximum ratings (AMR) All voltage values, except differential voltage, are with respect to network ground terminal. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. VCC -Vin must not exceed 6 V, Vin must not exceed 6 V. Input current must be limited by a resistor in series with the inputs. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values. 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. 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. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
