DESCRIPTION
The LPV511 is a micropower operational amplifier
that operates from a voltage supply range as wide as
2.7V to 12V with ensured 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 applications. In addition, the
output is capable of sourcing 650 µA of current when
powered by a 12V 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.
