LPV521 Datasheet (National Semiconductor Corporation)

LPV521, Operational Amplifier

The LPV521 is a single nanopower 552 nW amplifier designed 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 remote sensor nanopower applications.

The device has input common
