LMV851/LMV852/LMV854

8 MHz Low Power CMOS, EMI Hardened Operational

Amplifiers

General Description

Features

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.
