LPV521是一个单一的纳功率552纳瓦放大器超长电池寿命的应用而设计的。 1.6V至5.5V的工作电压范围，再加上通常351 nA电流，使其非常适合RFID阅读器和远程传感器纳功率应用供应。 该设备已在铁轨的输入共模电压0.1V，保证TCV OS和电压摆幅轨输出性能。 LPV521有一个精心设计的CMOS输入级，优于竞争对手一般为40 FA 我偏置电流。 这种低输入电流，大大减少了偏置我和我 OS兆欧电阻引入的误差，高阻抗光电二极管，和负责感的情况。 LPV521的PowerWise成员 ™ 家庭和有一个出色的功率性能比。
宽输入共模电压范围内，保证为1 mV V OS和3.5μV/ °彗星TCV的操作系统使高边和低边电流检测的准确和稳定的测量。
EMI protection is designed into devices, from mobile phones or other RFID readers, to reduce the sensitivity of unwanted RF signals.
The LPV521 is available in a 5-pin SC-70 package.
