LMV344-Q1 - Automotive Catalog Quad Rail-To-Rail Output CMOS Operational Amplifier with Shutdown

Updated : 2020-01-09 14:20:10
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 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. Additional features 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.

An extended industrial temperature range from –40°C to 125°C makes this device suitable for automotive applications.
