Dual Low Voltage
Operational Amplifier
LMV358
Dual Low Voltage Operational Amplifier
General Description
•
The LMV358 are low voltage (2.7-5.5V) versions of the dual
and quad commodity op amps.
•
The LMV358 are the most cost effective solutions for the
applications where low voltage operation, space saving and
low price are needed.
SOP-8
DIP-8
•
The LMV358 have rail-to-rail output swing capability and the
input common-mode voltage range includes ground. They all
exhibit excellent speed-power ratio, achieving 1MHz of bandwidth
MSOP-8
and 1V/µs of slew rate with low supply current.
•
The LMV358 have bipolar input and output stages for improved noise
performance and higher output current drive.
•
The LMV358 is available in SOP-8, DIP-8, TSSOP-8 and MSOP-8 packages
