7 title: Current Sense Amplifier
10 - Peter Rosin <peda@axentia.se>
13 When an io-channel measures the output voltage from a current sense
14 amplifier, the interesting measurement is almost always the current
15 through the sense resistor, not the voltage output. This binding
16 describes such a current sense circuit.
