The ISO212P signal isolation amplifier is a member of a series of low-cost isolation products from BurrBrown. The low-profile SIL plastic package allows PCB spacings of 0.5" to be achieved, and the small footprint results in efficient use of board space. To provide isolation, the design uses high-efficiency, miniature toroidal transformers in both the signal and power paths. An uncommitted input amplifier and an isolated external bipolar supply ensure the majority of input interfacing or conditioning needs can be met. The ISO212P accepts an input voltage range of 5V for single 15V supply operation or 3.0V for single 10V supply operation.
