LMV641

10 MHz, 12V, Low Power Amplifier

General Description

The LMV641 is a low power, wide bandwidth operational am-

plifier with an extended power supply voltage range of 2.7V

to 12V.

It features 10 MHz of gain bandwidth product with unity gain

stability on a typical supply current of 138

μA. Other key spec-

ifications are a PSRR of 105 dB, CMRR of 120 dB, V

500 μV, input referred voltage noise of 14 nV/

, and a THD

of 0.002%. This amplifier has a rail-to-rail output stage, and a

common mode input voltage which includes the negative sup-

ply.

The LMV641 operates over a temperature range of −40°C to

+125°C and is offered in the board space saving 5-Pin SC70

and 8-Pin SOIC packages.
