DESCRIPTION/ORDERING INFORMATION
The LMV341, LMV342, LMV344 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 1 pA (typ) and an offset voltage of 0.25 mV (typ). The single supply amplifier is designed
specifically for low-voltage (2.7 V to 5 V) operation, with a wide common-mode input voltage range that typically
extends from –0.2 V to 0.8 V 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 33 nA (typ).
Additional features of the family are a 20-nV/√Hz voltage noise at 10 kHz, 1-MHz unity-gain bandwidth, 1-V/µs
slew rate, and 100-µA current consumption per channel.
Offered in both the SOT-23 and smaller SC-70 packages, the LMV341 is suitable for the most space-constraint
applications. The LMV342 dual device is offered in the standard SOIC and MSOP 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.
