| 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>; |
| }; |
