3 Description
The LMV34x devices are single, dual, and quad
CMOS operational amplifiers, respectively, with low
voltage, low power, and rail-to-rail output swing
capabilities. The PMOS input stage offers an ultra-
low input bias current of 1pA (typical) and an
offset voltage of 0.25mV (typical). The single-supply
amplifier is designed specifically for low-voltage
(2.7V to 5V) operation, with a wide common-mode
input voltage range that typically extends from –0.2V
to 0.8V from the positive supply rail. The LMV341
(single) also offers a shutdown ( SHDN) pin that can
be used to disable the device. In shutdown mode, the
supply current is reduced to 33nA (typical). Additional
features of the family are a 20nV/√ Hz voltage noise
at 10kHz, 1MHz unity-gain bandwidth, 1V/μs slew
rate, and 100μA current consumption per channel.
Offered in both the SOT-23 and smaller SC70
packages, the LMV341 is suitable for the most space-
constraint applications. The LMV342 dual device is
offered in the standard SOIC and VSSOP packages.
An extended industrial temperature range from –40°C
to 125°C makes these devices suitable in a wide
variety of commercial and industrial environments.
