- Current Sense Amplifier
- =======================
- When an io-channel measures the output voltage from a current sense
- amplifier, the interesting measurement is almost always the current
- through the sense resistor, not the voltage output. This binding
- describes such a current sense circuit.
- Required properties:
- - compatible : "current-sense-amplifier"
- - io-channels : Channel node of a voltage io-channel.
- - sense-resistor-micro-ohms : The sense resistance in microohms.
- Optional properties:
- - sense-gain-mult: Amplifier gain multiplier. The default is <1>.
- - sense-gain-div: Amplifier gain divider. The default is <1>.
- Example:
- sysi {
- compatible = "current-sense-amplifier";
- io-channels = <&tiadc 0>;
- sense-resistor-micro-ohms = <20000>;
- sense-gain-mul = <50>;
- };
