  • Simple Circuit Delivers 38Vp-p at 5A from 28V Unipolar Supply
    PDF, 26 Kb, Datei veröffentlicht: Sep 27, 2000
    Since the first analog IC requiring bipolar supplies was developed, people have been trying to operate them from unipolar supplies. Not only do the headroom (VS - VOUTMAX) requirements come into play, but with a unipolar supply typically come unipolar outputs. To get bipolar output swings from a unipolar supply, drive the load differentially and create a reference signal wh
  • Boost Instrument Amp CMR With Common-Mode Driven Supplies
    PDF, 175 Kb, Datei veröffentlicht: Sep 27, 2000
    Ever-increasing demands are being placed on instrumentation amplifier (IA) performance. When standard IAs can not deliver the required performance, consider this enhanced version. Dramatic performance improvements can be achieved by operating the input amplifiers of a classical three-op-amp IA from common-mode driven sub-regulated power supplies.
