DESCRIPTION
The ISO212P signal isolation amplifier is a member of
a series of low-cost isolation products from Burr-
Brown. 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.
