LPV511
880 nA, Rail-to-Rail Input and Output Operational
Amplifier
General Description
The LPV511 is a micropower operational amplifier that op-
erates from a voltage supply range as wide as 2.7V to 12V
with guaranteed specifications at 3V, 5V and 12V. The
LPV511 exhibits an excellent speed to power ratio, drawing
only 880 nA of supply current with a bandwidth of 27 kHz.
These specifications make the LPV511 an ideal choice for
battery powered systems that require long life through low
supply current, such as instrumentation, sensor conditioning
and battery current monitoring.
The LPV511 has an input range that includes both supply
rails for ground and high side battery sensing applications.
The LPV511 output swings within 100 mV of either rail to
maximize the signal’s dynamic range in low supply applica-
tions. In addition, the output is capable of sourcing 650 µA of
current when powered by a 12V battery.
The LPV511 is available in the space saving SC70 package
which makes it ideal for portable electronics with area con-
strained PC boards.
