LMP7721是业界最低的保证输入偏置电流高精度放大器。 超低输入偏置电流是3发，保证限制的± 20 FA 25 ° C和± 900 FA 85 ° C。 这是最新的专利申请中的输入偏置电流消除放大器电路技术实现。 这项技术还保持超低对整个输入共模电压范围放大器的输入偏置电流。

Other outstanding features such as low voltage noise (6.5 NV / ），低直流偏移电压（± 150μV最大为25 ° C）和低失调电压的温度系数（-1.5μV/ ° C），提高系统的灵敏度，精度高，应用性和准确性。 随着电源电压范围为1.8V至5.5V，LMP7721是电池供电的便携式应用的理想选择。 LMP7721是LMP高精度放大器系列的一部分。

作为国家半​​导体的PowerWise产品的一部分，LMP7721提供了显着的宽增益带宽（GBW）17兆赫的产品的同时，耗电仅1.3毫安的电流。 这120分贝的高开环增益的GBW能够准确的信号调理。 有了这些规范，LMP7721到Excel中的电化学电池放大器和传感器接口电路等多种应用的性能。

LMP7721是一个特殊的引脚隔离电源放大器的输入和输出引脚提供8引脚SOIC封装。 有了正确的电路板布局技术，独特的LMP7721引出线防止到达输入引脚PCB漏电流。 因此，系统错误，将进一步减少。
