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.
