LMV861/LMV862
30 MHz Low Power CMOS, EMI Hardened Operational
Amplifiers
General Description
National’s LMV861 and LMV862 are CMOS input, low power
op amp IC's, providing a low input bias current, a wide tem-
perature range of −40°C to +125°C and exceptional perfor-
mance making them robust general purpose parts. Addition-
ally, the LMV861 and LMV862 are EMI hardened to minimize
any interference so they are ideal for EMI sensitive applica-
tions.
The unity gain stable LMV861 and LMV862 feature 30 MHz
of bandwidth while consuming only 2.25 mA of current per
channel. These parts also maintain stability for capacitive
loads as large as 200 pF. The LMV861 and LMV862 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 range
from 2.7V to 5.5V the LMV861 and LMV862 provide a PSRR
of 93 dB, and a CMRR of 93 dB. The LMV861 is offered in the
space saving 5-Pin SC70 package, and the LMV862 in the
8-Pin MSOP.
