Applications for a new power buffer

Jim Williams

A frequent requirement in systems involves driving analog signals into non-linear or reactive loads. Cables, transformers, actuators, motors and sample-hold circuits are examples where the ability to drive difficult loads is required. Although several power buffer amplifiers are available, none have been optimized for driving difficult loads. The LT®1010 can isolate and drive almost any reactive load. It also offers current limiting and thermal overload protection which protect the device against output fault conditions. The combination of good speed, output protection, and reactive load driving capability (see box section, “The LT1010 at a Glance”) make the device useful in a variety ...
