LMX358
Single/Dual/Quad, General-Purpose, Low-Voltage, Rail-to-Rail Output Op Amps
General Description
The LMX321/LMX358/LMX324 are single/dual/quad,
low-cost, low-voltage, pin-to-pin compatible upgrades
to the LMV321/LMV358/LMV324 family of general pur-
pose op amps. These devices offer rail-to-rail outputs
and an input common-mode range that extends below
ground. These op amps draw only 105µA of quiescent
current per amplifier, operate from a single +2.3V to
+7V supply, and drive 2kΩresistive loads to within
40mV of either rail. The LMX321/LMX358/LMX324 are
unity-gain stable with a 1.3MHz gain-bandwidth prod-
uct capable of driving capacitive loads up to 400pF.
The combination of low voltage, low cost, and small
package size makes these amplifiers ideal for
portable/battery-powered equipment.
The LMX321 single op amp is available in ultra-small 5-
pin SC70 and space-saving 5-pin SOT23 packages. The
LMX358 dual op amp is available in the tiny 8-pin SOT23
or the 8-pin µMAX® package. The LMX324 quad op amp
is available in 14-pin TSSOP and SO packages.
