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
puts and an input common-mode range that extends
below ground. These op amps draw only 105µA of qui-
escent current per amplifier, operate from a single
+2.3V to +7V supply, and drive 2k
within 40mV of either rail. The LMX321/LMX358/LMX324
are unity-gain stable with a 1.3MHz gain-bandwidth
product 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 package. The LMX324 quad op amp is avail-
able in 14-pin TSSOP and SO packages.
