DESCRIPTION
TI’s LMV861 and LMV862 are CMOS input, low
power op amp IC's, 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 LMV861 and LMV862
are EMI hardened to minimize any interference so
they are ideal for EMI sensitive applications.
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 VSSOP.
