FEATURES

DESCRIPTION

The LPV511 is a micropower operational amplifier

2

(Typical at 3V Supply Unless Otherwise Noted)

that operates from a voltage supply range as wide as

•

Wide Supply Voltage Range 2.7V to 12V

2.7V to 12V with ensured specifications at 3V, 5V and

•

Slew Rate 7.7 V/ms

12V. The LPV511 exhibits an excellent speed to

power ratio, drawing only 880 nA of supply current

•

Supply Current 880 nA

with a bandwidth of 27 kHz. These specifications

•

Output Short Circuit Current 1.35 mA

make the LPV511 an ideal choice for battery powered

•

Rail-to-Rail Input

systems that require long life through low supply

current, such as instrumentation, sensor conditioning

•

Rail-to-Rail Output 100 mV from Rails

and battery current monitoring.

•

The LPV511 has an input range that includes both

•

Unity Gain Stable

supply rails for ground and high side battery sensing

applications. The LPV511 output swings within 100

process.

•

Portable Instrumentation

The LPV511 is available in the space saving SC70

•

Micropower Filter

package which makes it ideal for portable electronics

•

Remote Sensor Amplifier

with area constrained PC boards.
