Nanopower, 1.8V, RRIO, CMOS Input, Operational

Amplifier

General Description

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

TCV

LPV521 has a carefully designed CMOS input stage that out-

performs competitors with typically 40 fA I

low input current significantly reduces I

troduced in megohm resistance, high impedance photodiode,

and charge sense situations. The LPV521 is a member of the

PowerWise

mance ratio.

The wide input common mode voltage range, guaranteed 1

mV V

measurement for both high side and low side current sensing.

EMI protection was designed into the device to reduce sen-

sitivity to unwanted RF signals from cell phones or other RFID

readers.

The LPV521 is offered in the 5-pin SC-70 package.
