2 Description

The LMV341 and LMV344 devices are single 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 –0.2Vto 0.8V

from the positive supply rail. Additional features are

a 20nV/√ Hz voltage noise at 10kHz, 1MHz unity-

gain bandwidth, 1V/μs slew rate, and 100μA current

consumption per channel.

An extended industrial temperature range from –40°C

to 125°C makes this device an excellent choice for

automotive applications.
