Scope
This application note describes a simple add-on circuit for extracting current to supply external loads. It also
includes hardware description ,schematic and Vout/Iout curves.
KEY FEATUREs
• Only few additional low-cost components necessary
• Can drive line currents up to ILine-5mA (=15mA for 20mA line current)
• No influence in AC impedance or DC mask even when load is short circuited
