LMV721/LMV722
10MHz, Low Noise, Low Voltage, and Low Power
Operational Amplifier
General Description
The LMV721 (Single) and LMV722 (Dual) are low noise, low
voltage, and low power op amps, that can be designed into a
wide range of applications. The LMV721/LMV722 has a unity
gain bandwidth of 10MHz, a slew rate of 5V/us, and a quies-
cent 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 provide
rail-to-rail output swing into heavy loads. The input common-
mode voltage range includes ground, and the maximum input
offset voltage are 3.5mV (Over Temp.) for the LMV721/
LMV722. Their capacitive load capability is also good at low
supply voltages. The operating range is from 2.2V to 5.5V.
The chip is built with National's advanced Submicron Silicon-
Gate BiCMOS process. The single version, LMV721, is avail-
able in 5 pin SOT23-5 and a SC-70 (new) package. The dual
version, LMV722, is available in a SO-8, MSOP-8 and 8-pin
LLP package.
