3 Description
The LPV511 is a micropower operational amplifier
that operates from a voltage supply range as wide as
2.7 V to 12 V with ensured specifications at 3 V, 5 V,
and 12 V. The ultra-low power 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 applications. In addition, the
output is capable of sourcing 650 μA of current when
powered by a 12-V battery.
The LPV511 is fabricated on TI's advanced VIP50C
process.
The LPV511 is available in the space-saving SC70
package, which makes it ideal for portable electronics
with area-constrained PC boards.
