LF356 Wide Range Current-To-Voltage Converter

Current to voltage converter circuit can be made using a single resistor, it is very simple since any current will naturally develop a voltage when flow through a resistor. Using an active component,  a small developed voltage on a resistor can be accurately measured since we can amplify it to reach a convenient level to be measured. A schematic diagram […]

Differential Current Sensing Inside H Bridge

A differential current sensing that is inserted inside a H bridge circuit. is shown in the schematic diagram below. This circuit is one example of AD8205 application. The AD8205 measures current in both directions as the motor changes direction and H-bridge switches. This circuit has high accuracy in current measurement because AD8205 is placed in the middle of the H-bridge. […]

High Side Current Sensing for High Side Switching

Sometimes, there are unexpected solenoid and excessive corrosion occurs on current sense circuit. Corrosive effects can be occurred because of the differential voltage between the ground and the load. To reduce that possibility, the shunt and the switch are placed on the high side. When switch is off, the battery is removed from the load, it will avoid damage from […]

High Side Current Sensing for Low Side Switching

An AD8205 can be used to make a high-side current sense with a low side switch. Besides AD8205, an inductive load (solenoid) and a resistive shunt are added in this circuit. The resistive shunt is placed on high-side and the switch is placed on low-side, so that all current measurements, including the the re-circulation current, can be done because when […]

Moving-Coil Meter with Separate Supply using INA193

The digital meters is lack of accuracy and resolution in comparison to drawing information upon a measurement’s rate of change or tracking a reading’s trend. To solve this problem, we should use analog moving-coil meters. Here is the schematic diagram of analog moving-coil meters : This circuit uses 8-inch moving coil meter with a measuring current range from 0 to […]
