LPV511

Micropower, Rail-to-Rail Input and Output Operational

Amplifier

General Description

The LPV511 is a micropower operational amplifier that oper-

ates 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 spec-

ifications make the LPV511 an ideal choice for battery pow-

ered systems that require long life through low supply current,

such as instrumentation, sensor conditioning and battery cur-

rent 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 ad-

dition, the output is capable of sourcing 650 µA of current

when powered by a 12V battery.

The LPV511 is fabricated on National's advanced VIP50C

process.

The LPV511 is available in the space saving SC70 package

which makes it ideal for portable electronics with area con-

strained PC boards.
