What the LMV358 does
The LMV358 is a low-power dual operational amplifier available in standard and low-voltage variants. It operates on a single supply of 2.7 to 5.5 volts and features a typical gain bandwidth product of 1 MHz. The device includes a quiescent current of 100 microamps per amplifier and an output swing capable of reaching within 150 millivolts of ground. Engineers typically use this component in battery-powered portable devices, low-voltage sensor interfaces, and general-purpose signal conditioning circuits where power efficiency is critical.
