LMV422 Datasheet | National Semiconductor

Description The LMV422 dual rail-to-rail output amplifier offers a power select pin (PS) that allows the user to select one of two power modes depending on the level of performance desired. This is ideal for AC coupled circuits where the circuit needs to be kept active to maintain a quiescent charge on the coupling capacitors with minimum power consumption. For portable applications, the LMV422 operates in low power mode consuming only 2 µA of supply current per channel at a bandwidth of 27 k Hz. This allows the user to reduce the power consumption of an amplifier while maintaining an active circuit. For additional bandwidth and output current drive the amplifier can be switched to full power mode with 8 MHz bandwidth while consuming only 400 µA per channel. The LMV422 features a rail-to-rail output voltage swing in addition to an input mon mode range that includes ground. The LMV422 is designed for closed loop gains of plus two (or minus one) or greater. The LMV422 is offered in 10-Pin MSOP miniature package to ease the adoption in applications where board area is at a premium.
