LMV851/LMV852/LMV854
8 MHz Low Power CMOS, EMI Hardened Operational
Amplifiers
General Description
National’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 per-
formance, making them robust general purpose parts. Addi-
tionally, 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 maxi-
mum 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 MSOP
and the 14-Pin TSSOP package.
