A SIMPLE ALTERNATIVE TO ANALOG ISOLATION AMPLIFIERS 1. Introduction Analog circuits sometimes require linear (analog) signal isolation for safety, signal level shifting, and/or ground loop elimination. Linear signal isolation is typically difficult to implement, costly, and often exhibits mediocre performance. While the design munity thirsts for a flexible and inexpensive linear isolator solution, it is the analog isolation amplifier (ISOamp) that most often captures the socket. ISOamps are hybridized devices that contain linear input and output circuits separated by an internal isolation barrier. ISOamps typically modulate the linear input signal and transmit the resulting...
