Application Notes
- High-Voltage Signal Conditioning for Low Voltage ADCsPDF, 135 Kb, File published: Jun 15, 2004
Analog designers are frequently required to develop circuits that convert high-voltage signals to levels acceptable for low-voltage data converters. This paper describes several solutions for this common task using modern amplifiers and typical power supplies. Five examples of conditioning ±10V bipolar signals for low-voltage single-rail analog-to-digital converters(ADCs) are presented:
