LPV521  
Nanopower, 1.8V, RRIO, CMOS Input, Operational  
Amplifier  
General Description  
Features  
The LPV521 is a single nanopower 552 nW amplifier de-  
signed for ultra long life battery applications. The operating  
voltage range of 1.6V to 5.5V coupled with typically 351 nA of  
supply current make it well suited for RFID readers and re-  
mote sensor nanopower applications. The device has input  
common mode voltage 0.1V over the rails, guaranteed  
TCVOS and voltage swing to the rail output performance. The  
LPV521 has a carefully designed CMOS input stage that out-  
performs competitors with typically 40 fA IBIAS currents. This  
low input current significantly reduces IBIAS and IOS errors in-  
troduced in megohm resistance, high impedance photodiode,  
and charge sense situations. The LPV521 is a member of the  
PowerWise® family and has an exceptional power-to-perfor-  
mance ratio.
