LMP8603QMA/NOPB 3 Description

The LMP8601, LMP8602, LMP8603 (LMP860x) andLMP8601-Q1,LMP8603-Q1LMP8602-Q1,(LMP860x-Q1) devices are fixed-gain, precisioncurrent-sense amplifiers (also referred to as current-shunt monitors). The input common-mode voltagerange is –22 V to +60 V when operating from a single5-V supply, or –4 V to +27 V with a 3.3-V supply. TheLMP860x and LMP860x-Q1 are ideal parts forsensingunidirectionalapplications.bidirectionalcurrentandThese devices have a precise gain of 20x (LPM8601,LPM8601-Q1), 50x (LPM8602, LPM8602-Q1), and100x (LPM8603, LPM8603-Q1), and are adequate inmost targeted applications to drive an ADC to full-scale value. The fixed gain is achieved in twoseparate stages: a preamplifier with a gain of 10x andan output stage buffer amplifier with a gain of 2x(LMP8601, LMP8601-Q1), 5x (LMP8602, LMP8602-Q1), or 10x (LMP8603, LMP8603-Q1). The pathbetween the two stages is brought out on two pins toenable the option of an additional filter network ormodifying the gain.The offsetinput pin enables these devices forunidirectional or bidirectional single supply voltagecurrent sensing.The LMP860x-Q1 devices incorporate enhancedmanufacturing and support processestheautomotive market and are compliant with the AEC-Q100 standard.forDevice Information(1)Typical Applications
