LPV801(单通道)和 LPV802(双通道)组成了超低功耗运算放大器系列,适用于由电池供电的无线和低功耗有线设备 中的 感测应用。LPV80x 放大器的带宽为 8kHz,静态电流为 320nA,可最大限度降低运行电池寿命至关重要的设备(如 CO 检测器、烟雾检测器和 PIR 运动检测器)消耗的功率。
除超低功耗特性外,LPV80x 放大器还具有实现毫微微安偏置电流的 CMOS 输入级。LPV80x 放大器还特有一个负轨感测输入级和一个相对于电源轨的摆幅为毫伏级的轨到轨输出级,从而尽可能保持最宽的动态范围。LPV80x 设有电磁干扰 (EMI) 保护,可降低来自手机、WiFi、无线电发射器和标签阅读器的无用射频信号对系统造成的影响。
