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.

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
