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.
