DESCRIPTION
TI’s LMV831, LMV832, and LMV834 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
LMV831/LMV832/LMV834 are EMI hardened to
minimize any interference so they are ideal for EMI
sensitive applications.
The unity gain stable LMV831/LMV832/LMV834
feature 3.3 MHz of bandwidth while consuming only
0.24 mA of current per channel. These parts also
maintain stability for capacitive loads as large as 200
pF. The LMV831/LMV832/LMV834 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 LMV831/LMV832/LMV834 provide a PSRR of 93
dB, and a CMRR of 91 dB. The LMV831 is offered in
the space saving 5-Pin SC70 package, the LMV832
in the 8-Pin VSSOP and the LMV834 is offered in the
14-Pin TSSOP package.
