The – Supply Current at VCM = 0.3 V 400 nA (Max) operating voltage range of 1.6 V to 5.5 V coupled – Operating Voltage Range 1.6 V to 5.5 V with typically 351 nA of supply current make it well suited for RFID readers and remote sensor – Low TCVOS 3.5 µV/°C (Max) nanopower applications. The device has input – VOS 1 mV (Max) common mode voltage 0.1 V over the rails, – Input Bias Current 40 fA guaranteed TCVOS and voltage swing to the rail output performance. The LPV521 has a carefully – PSRR 109 dB designed CMOS input stage that outperforms – CMRR 102 dB competitors with typically 40 fA IBIAS currents. This – Open-Loop Gain 132 dB low input current significantly reduces IBIAS and IOS errors introduced in megohm resistance, high – Gain Bandwidth Product 6.2 kHz impedance photodiode, and charge sense situations. – Slew Rate 2.4 V/ms The LPV521 is a member of the PowerWise™ family – Input Voltage Noise at f = 100 Hz 255 nV/ √Hz and has an exceptional power-to-performance ratio. – Temperature Range −40°C to 125°C The wide input common mode voltage range, guaranteed 1 mV VOS and 3.5 µV/°C TCVOS enables 2 Applications accurate and stable measurement for both high-side and low-side current sensing. • Wireless Remote Sensors • Powerline Monitoring EMI protection was designed into the device to reduce sensitivity to unwanted RF signals from cell • Power Meters phones or other RFID readers. • Battery Powered Industrial Sensors The LPV521 is offered in the 5-pin SC70 package. • Micropower Oxygen sensor and Gas Sensor • Active RFID Readers Device Information(1) • Zigbee Based Sensors for HVAC Control PART NUMBER PACKAGE BODY SIZE (NOM) • Sensor Network Powered by Energy Scavenging LPV521 SC70 (5) 2.00 mm x 1.25 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
