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.
