LPV511

880 nA, Rail-to-Rail Input and Output Operational

Amplifier

General Description

Features

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.

27 kHz

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.

Applications

n Battery powered systems

n Security systems

n Micropower thermostats

n Solar powered systems

n Portable instrumentation

n Micropower filter

The LPV511 is available in the space saving SC70 package

which makes it ideal for portable electronics with area con-

strained PC boards.

n Remote sensor amplifier
