Texas Instruments LPV801和LPV802毫微功耗运算放大器

Texas Instruments LPV801和LPV802毫微功耗运算放大器是超低功率运算放大器,用于电池供电无线设备和低功耗有线设备中的感测应用。LPV80x放大器能够为注重电池运行寿命的设备(例如CO探测器、烟雾检测器和PIR运动检测器)将功耗降至最低。LPV80在320nA静态电流下的带宽为8kHz。

These Texas Instruments LPV80x amplifiers have CMOS input stages with typically femtoamp bias currents and feature a negative-rail sensing input stage and a rail-to-rail output stage. This stage is capable of swinging within millivolts of the rails, maintaining the widest dynamic range possible. EMI protection is designed into the LPV80x to reduce system sensitivity to unwanted RF signals from mobile phones, Wi-Fi, radio transmitters, and tag readers.
