3 Description
The LMV641 is a low-power, wide-bandwidth
operational amplifier with an extended power supply
voltage range of 2.7 V to 12 V.
The device features 10 MHz of gain bandwidth
product with unity gain stability on a typical supply
current of 138 μA. Other key specifications are a
PSRR of 105 dB, CMRR of 120 dB, VOS of 500 μV,
input referred voltage noise of 14 nV/√Hz, 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 supply.
The LMV641 device operates over a temperature
range of −40°C to +125°C and is offered in the boardspace-
saving 5-Pin SC70, SOT-23, and 8-Pin SOIC
packages.
