TIPD135, 10 A-100 mA, 0.05% Error, High-Side Current Sensing
참조 설계 작성자: Texas Instruments
TIPD135, This Precision Verified Design provides theory, component selection, simulation, complete PCB schematic and layout, bill of materials, and measured performance of a split-supply, high-side four decade current sensing solution that can accurately detect load currents from 10uA-100mA. The corresponding linear output is from 10mV to 4.9V which enables measurement by common 5V ADCs. The design utilizes the PGA281, an instrumentation amplifier with pin-programmable gain and a wide common-mode voltage range, to provide a more accurate and versatile solution than traditional Op-Amps
