LMV831/LMV832/LMV834
3 MHz Low Power CMOS, EMI Hardened Operational
Amplifiers
General Description
National’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. Ad-
ditionally, the LMV831/LMV832/LMV834 are EMI hardened
to minimize any interference so they are ideal for EMI sensi-
tive applications.
The unity gain stable LMV831/LMV832/LMV834 feature
3.3 MHz of bandwidth while consuming only 0.24 mA of cur-
rent per channel. These parts also maintain stability for ca-
pacitive 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 MSOP and the LMV834 is offered in the 14-Pin TSSOP
package.
