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/
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.
