AD215: 隔离放大器
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 wide-band 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 out-put with offset trim and a user-available isolated front-end power supply which produces ±15 V dc at ±10 mA.
