DESCRIPTION/ORDERING INFORMATION

The LMV721 (single) and LMV722 (dual) are low-noise low-voltage low-power operational amplifiers that can be

designed into a wide range of applications. The LMV721 and LMV722 have a unity-gain bandwidth of 10 MHz, a

slew rate of 5 V/ms, and a quiescent current of 930 mA/amplifier at 2.2 V.

The LMV721 and LMV722 are designed to provide optimal performance in low-voltage and low-noise systems.

They provide rail-to-rail output swing into heavy loads. The input common-mode voltage range includes ground,

and the maximum input offset voltage are 3.5 mV (over recommended temperature range) for the devices. Their

capacitive load capability is also good at low supply voltages. The operating range is from 2.2 V to 5.5 V.
