Boosting output in high-voltage op-amps with a current buffer

Joe Kyriakakis, Apex Microtechnology

Delivering more than 200mA of output current can be a serious challenge for many high-voltage operational amplifiers. But for high voltage applications requiring as much as 1A of current, it is possible to meet this spec by pairing a current buffer with the op amp. What the current buffer brings to this arrangement is

Powering low-voltage devices from an intermediate-bus voltage

Willie Chan & Jason Sekanina, Linear Technology

Intermediate bus voltages from 24V to 28V (nominal) are commonplace in industrial, aerospace and defense systems, where series-connected batteries may be a backup power source and 12V bus architectures tend to be impractical due to distribution losses. The widening voltage gap between the system bus and the po
