Application Notes
- Simple Circuit Delivers 38Vp-p at 5A from 28V Unipolar SupplyPDF, 26 Kb, File published: 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 SuppliesPDF, 175 Kb, File published: 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. - Optoelectronics Circuit CollectionPDF, 261 Kb, File published: Jun 11, 2001
This application report presents a collection of analog circuits that may be useful in electro-optic applications such as optical networking. The circuits are Avalanche Photodiode Bias Supply 1; Linear TEC Driver-1, -2, and -3; Laser Diode Driver-1 and -2; and Temperature Under- and Over-range Sensing with a Window Comparator.
