DESCRIPTION

The LMV881 is a low power CMOS input operational

amplifier that provides low input bias currents, a rail

to rail output with high output drive capability and a

wide temperature range of −40°C to +125°C.

Additionally, the LMV881 is EMI hardened to

minimize sensitivity to external interference.

The LMV881 has a maximum input offset voltage of 1

mV with an input common-mode voltage range that

includes ground. Over an operating supply range

from 2.7V to 5.5V, the LMV881 provides a typical

PSRR of 110dB and a CMRR of 110dB. This makes

the LMV881 ideal for EMI sensitive applications as

well as exceptional performance as a robust general

purpose part.

The unity gain stable LMV881 features 23 MHz of

bandwidth while consuming only 1.65 mA of current.

This device also maintains stability for capacitive

loads as large as 200 pF.
