DESCRIPTION
ISO213 signal isolation amplifier is a member of a
series of low-cost isolation products from Burr-Brown.
The low-profile ZIP plastic package allows PCB spac-
ings 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 instrumentation ampli-
fier on the input and an isolated external bipolar supply
ensure the majority of input interfacing or conditioning
needs can be met.
