LPV521

SNOSB14D –AUGUST 2009–REVISED DECEMBER 2014

LPV521 NanoPower, 1.8-V, RRIO, CMOS Input, Operational Amplifier

1 Features

3 Description

The LPV521 is a single nanopower 552-nW amplifier

designed for ultra long life battery applications. The

operating voltage range of 1.6 V to 5.5 V coupled

with typically 351 nA of supply current make it well

suited for RFID readers and remote sensor

nanopower applications. The device has input

V_OS1 mV (Max)

common mode voltage 0.1

V over the rails,

Input Bias Current 40 fA

guaranteed TCV_OSand voltage swing to the rail

output performance. The LPV521 has a carefully

designed CMOS input stage that outperforms

competitors with typically 40 fA I_BIAScurrents. This

low input current significantly reduces I_BIASand I_OS

errors introduced 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-performance ratio.

PSRR 109 dB

CMRR 102 dB

Open-Loop Gain 132 dB

Gain Bandwidth Product 6.2 kHz

Slew Rate 2.4 V/ms

Input Voltage Noise at f = 100 Hz 255 nV/√Hz

Temperature Range −40°C to 125°C

The wide input common mode voltage range,

guaranteed 1 mV V_OSand 3.5 µV/°C TCV_OSenables

accurate and stable measurement for both high-side

and low-side current sensing.

2 Applications

•

Wireless Remote Sensors

Powerline Monitoring

EMI protection was designed into the device to

reduce sensitivity to unwanted RF signals from cell

phones or other RFID readers.

Power Meters

Battery Powered Industrial Sensors

Micropower Oxygen sensor and Gas Sensor

Active RFID Readers

The LPV521 is offered in the 5-pin SC70 package.
