DESCRIPTION
Texas Instrument’s LMV851/LMV852/LMV854 are
CMOS input, low power op amp ICs, providing a low
input bias current, a wide temperature range of
−40°C to +125°C and exceptional performance,
making them robust general purpose parts.
Additionally, the LMV851/LMV852/LMV854 are EMI
hardened to minimize any interference so they are
ideal for EMI sensitive applications. The unity gain
stable LMV851/LMV852/LMV854 feature 8 MHz of
bandwidth while consuming only 0.4 mA of current
per channel. These parts also maintain stability for
capacitive loads as large as 200 pF. The
LMV851/LMV852/LMV854
provide
superior
performance and economy in terms of power and
space usage. This family of parts has a maximum
input offset voltage of 1 mV, a rail-to-rail output stage
and an input common-mode voltage range that
includes ground. Over an operating supply range
from 2.7V to 5.5V the LMV851/LMV852/LMV854
provide a CMRR of 92 dB, and a PSRR of 93 dB.
The LMV851/LMV852/LMV854 are offered in the
space saving 5-Pin SC70 package, the 8-Pin VSSOP
and the 14-Pin TSSOP package.
