The innovative circuit and transformer design of the AD215 ensures wideband dynamic characteristics while preserving key dc performance specifications. The AD215 provides plete galvanic isolation between the input and output of the device including the user-available front-end isolated power supplies. The functionally plete 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 plexity and ponent 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 mon-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 m A.
