LMV721 General Description


The LMV721 (Single) and LMV722 (Dual) are low noise, lowvoltage, and low power op amps, that can be designed intoa wide range of applications. The LMV721/LMV722 has aunity gain bandwidth of 10MHz, a slew rate of 5V/us, and aquiescent current of 930uA/amplifier at 2.2V.

The LMV721/722 are designed to provide optimal perfor-mance in low voltage and low noise systems. They providerail-to-rail output swing into heavy loads. The inputcommon-mode voltage range includes ground, and themaximum input offset voltage are 3.5mV (Over Temp.) forthe LMV721/LMV722. Theircapacitive load capability is alsogood at low supply voltages. The operating range is from2.2V to 5.5V.

The chip is built with National's advanced SubmicronSilicon-Gate BiCMOS process. The single version, LMV721,is available in 5 pin SOT23-5 and a SC-70 (new) package.

The dual version, LMV722, is available in a SO-8 and MSOP-8 package.
