LPV521MGE/NOPB General 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 common mode voltage 0.1 V over the rails, guaranteed TCV_OS and voltage swing to the rail output performance. The LPV521 has a carefully designed CMOS input stage that outperforms competitors with typically 40 fA I_BIAS currents. This low input current significantly reduces I_BIAS and 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.

The wide input common mode voltage range, guaranteed 1 mV V_OS and 3.5 µV/°C TCV_OS enables accurate and stable measurement for both high-side and low-side current sensing.

EMI protection was designed into the device to reduce sensitivity to unwanted RF signals from cell phones or other RFID readers.

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

The screens arrived successfully but the packaging is very poor. They come in a thin bubble wrap. The screens are independently packed in anti static bag. Not tested yet.
