1Current Sense Amplifier 2======================= 3 4When an io-channel measures the output voltage from a current sense 5amplifier, the interesting measurement is almost always the current 6through the sense resistor, not the voltage output. This binding 7describes such a current sense circuit. 8 9Required properties: 10- compatible : "current-sense-amplifier" 11- io-channels : Channel node of a voltage io-channel. 12- sense-resistor-micro-ohms : The sense resistance in microohms. 13 14Optional properties: 15- sense-gain-mult: Amplifier gain multiplier. The default is <1>. 16- sense-gain-div: Amplifier gain divider. The default is <1>. 17 18Example: 19 20sysi { 21 compatible = "current-sense-amplifier"; 22 io-channels = <&tiadc 0>; 23 24 sense-resistor-micro-ohms = <20000>; 25 sense-gain-mul = <50>; 26}; 27
