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.
