WebNov 4, 2014 · A voltage divider is implemented for each of the inputs because the current sensor needs to be able to measure current when the load is on the high side as well as on the low side. Without the voltage divider, +IN gets pulled to 14V and a voltage greater than 14V gets produced internally in the LT1167. WebThe voltage across the shunt is proportional to the current flowing through it, and so the measured voltage can be scaled to directly display the current value. Shunts are rated by maximum current and voltage drop at that …

WebCareful consideration of the shunt resistor (R SENSE) is an important and necessary part of designing any kind of current monitor. The following criteria should govern the selection of R SENSE: Voltage Loss: High R SENSE values cause the power-source voltage to degrade through IR loss. The lowest R SENSE value gives the least voltage loss. WebThe common and simple approach to current sensing is the use of a shunt resistor. The voltage drop across the shunt is proportional to its current flow. Both alternating currents (AC) and direct currents (DC) can be measured with the shunt resistor. captain randy sanibel islandWebThe upper circuit (a) uses an instrumentation amplifier (IA) powered by a separate rail (>1V above V IN) to measure across the 1kΩ current shunt. The lower figure (b) is similar but derives its power supply from the APD bias line. The limitation of these circuits is the 35V maximum APD voltage, whereas some APDs may require 90V or more. captain ranking in cricket
