Feasible basic set-ups · Wiring with the programming pc board

We can precisely adapt these controllable power supply units to your application by the way we wire the programming circuit board. The following circuits show the basic functions which can be realised with all power amplifiers. Various circuits can also be combined together and extended to form more complicated functions. For example, an integrator can also be extended with a differential input circuit to form a differential input integrator.
Microvolts at the difference input
The greater the degree of amplification, the smaller the input differential voltage and the more accurate the analogue, mathematical operations. One of the key quality criteria in this respect is the level of microvolts at the input.
