Description
The 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 can drive capacitive loads. The
devices are stable while operating at unity gain.
They are offered with industry standard pinouts in
tiny packages.

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. R

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.

4 Application information
4.1 Operating voltages
The LMX321, LMX358 and LMX324 can operate from 2.3 to 5.5 V. The devices’ parameters
are fully specified for 2.7 and 5 V power supplies. Additionally, the main specifications are
guaranteed in extended temperature ranges from -40° C to +125° C.
4.2 Input common-mode range
The LMX321, LMX358 and LMX324 have an input common-mode range that includes
ground. The input common-mode range is extended from V
output phase reversal.
4.3 Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: 180 mV maximum above
and below the rail when connected to a 10 kΩ resistive load to

4.5 PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
4.6 Macromodel
Accurate macromodels of the LMX321, LMX358 and LMX324 are available on
STMicroelectronics’ web site at www.st.com. This model is a trade-off between accuracy
and complexity (that is, time simulation) of the LMX321, LMX358 and LMX324 operational
amplifiers. It emulates the nominal performances of a typical device within the specified
operating conditions mentioned in the datasheet. It also helps to validate a design approach
and to select the right operational amplifier, but it does not replace on-board measurements.
