Shunts, Shunt Resistors & Current Shunts RS

Webb1 apr. 2024 · The most straightforward is to remember Ohm’s law: a current (I) flowing through a resistor (R) will generate a voltage (V) across the terminals of the resistor, simply calculated as V = R × I. So, a simple shunt resistor can transform a current into a voltage, and this voltage can then be measured by an oscilloscope. Webb11 nov. 2024 · The input bias current is low enough for your needs, and being limited to +/- 5 V on a TIA trying to measure very small currents is a problem. If this is for a high volume product, fair enough, otherwise, how much pain are you willing to go through to save a few bucks? What you get for the money is +/- 15V rails and a more stable amp. \$\endgroup\$ chinese sympathy plants
