Read moreDigital transmission isolation is important for keeping the digital noise to reach the analog path, that’s the benefit for noise isolation. For electrical isolation, isolating the signal after digitizing is often easier since digital signal is inherently nonlinear, no need for linear device to transfer. You can use the following circuit for many purpose: [Source: National Semiconductor Application Note]
Read moreMagnetic transducer is usually found in pulse counting application, and we can use this circuit to amplify and convert the signal from the transducer. Here is the schematic diagram of the signal conditioning circuit: [Source: National Semiconductor Application Note]
