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.
