App note from Apex Microtechnology on determining the full bandwidth of high power op amp. Link here (PDF) Getting the highest bandwidth out of a Power Op Amp is one of the most common challenges in highpower analog. Whether you’re outputting a 3 MHz sinewave into a semiconductor during testing, or getting the sharpest corners […]

App note: Optimizing output power of power op amps
Enhancing the performance of power op amps discussed in this app note from Apex Microtechnology. Link here (PDF) Power op amps are attractive because they reduce circuit design time enormously. Assembly costs of the power op amp design amount to a fraction of the discrete counterpart due to vastly reduced parts count. Careful attention to […]
App note: PWM Basics
PWM basics and PWM drivers app note from APEX Microtechnology. Link here (PDF) PWM circuits are taking the same general course of development traveled by op amps and many other electronic functions. Concepts were brought to life using discrete components and were followed by modules, hybrids and then monolithics.
App note: Voltage to current conversion
Using Apex Microtechnology’s power op amps for voltage controlled current sources (VCCS’s) application note, Link here (PDF) Voltage controlled current sources (or VCCS’s) can be useful for applications such as active loads for use in component testing or torque control for motors. Torque control is simplified since torque is a direct function of current in […]
App note: Programmable power supplies
Apex Microtechnology’s application note about programmable power supplies. Link here (PDF) The programmable power supply (PPS) is not only a key element in automated test equipment, but it is also used in fields as diverse as industrial controls, scientific research and vehicular controls. When coupled to a computer, it bridges the gap from the software […]
