Dual, General Purpose, Low Cost, RRO Amplifier

 
DescriptionThe LMV321 (single), LMV358 (dual), and LMV324 (quad)are a low cost, voltage feedback amplifiers that consume only80μA of supply current per amplifier. The LMV3XX familyis designed to operate from 2.7V (±1.35V) to 5.5V (±2.75V)supplies. The common mode voltage range extends below thenegative rail and the output provides rail-to-rail performance.The LMV3XX family is designed on a CMOS process andprovides 1.2MHz of bandwidth and 1.5V/μs of slew rate at alow supply voltage of 2.7V. The combination of low power,rail-to-rail performance, low voltage operation, and tiny pack-age options make the LMV3XX family well suited for use inpersonal electronics equipment such as cellular handsets,pagers, PDAs, and other battery powered applications.

The LMV321/LMV358/LMV324 are low voltage (2.7V to 5.5V)
single, dual and quad operational amplifiers. The
LMV321/LMV358/LMV324 are designed to effectively reduce cost
and space at low voltage levels. These devices have the
capability of rail-to-rail output swing and input common-mode
voltage range includes ground. They can also achieve an efficient
speed-to-power ratio, utilizing 1 MHz bandwidth and 1 V/μs slew
rate at a low supply current. Reducing noise pickup and
increasing signal integrity can be achieved by placing the device
close to the signal source. The LMV321 is available in 5-Pin
SOT353/SOT25 packages that reduce space on pc boards
and portable electronic devices. The LMV324 is available in the
TSSOP-14L package. The LMV358 is available in the MSOP-8L
and SOP-8L packages.
