With 8kHz of bandwidth from 320nA of quiescent current, the LPV80x amplifiers minimize power consumption in equipment such as CO detectors, smoke detectors and PIR motion detectors where operational battery-life is critical. In addition to being ultra-low-power, the LPV80x amplifiers have CMOS input stages with typically femto-amp bias currents. The LPV80x amplifiers also feature a negative-rail sensing input stage and a railto-rail output stage that is capable of s...
