AD215,pdf datasheet (Isolation

The AD215 is a high speed input isolation amplifier designed to
isolate and amplify wide bandwidth analog signals. The innovative
circuit and transformer design of the AD215 ensures wideband
dynamic characteristics while preserving key dc performance
specifications.
The AD215 provides complete galvanic isolation between the
input and output of the device including the user-available
front-end isolated power supplies. The functionally complete
design, powered by a ±15 V dc supply, eliminates the need for a
user supplied isolated dc/dc converter. This permits the designer
to minimize circuit overhead and reduce overall system design
complexity and component costs.
The design of the AD215 emphasizes maximum flexibility and
ease of use in a broad range of applications where fast analog
signals must be measured under high common-mode voltage
(CMV) conditions. The AD215 has a ±10 V input/output
range, a specified gain range of 1 V/V to 10 V/V, a buffered output
with offset trim and a user-available isolated front-end
power supply which produces ±15 V dc at ±10 mA.
