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.
