Reference Designs

This TI Precision Verified Design provides the 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.See more TI Precision Designs
