Isolation Techniques for Signal Conditioning
Industrial environments present a formidable challenge to the electronic system designer. In particular, high electrical noise levels and often excessive common mode voltages make safe, precise measurement difficult. One of the best ways to overcome these problems is by the use of isolated measurement techniques. Typically, these approaches utilize transformers or opto isolators to galvanically isolate the input terminals of the signal conditioning amplifier from its output terminal. This breaks the common ground connection and eliminates noise and dangerous common mode voltages. The conflicting requirements for good accuracy and total input/output galvanic isolation requires unusual circuit techniqu……
