  • High-Voltage Signal Conditioning for Low Voltage ADCs
    PDF, 135 Kb, Archivo publicado: 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:
  • Precision Absolute Value Circuits
    PDF, 100 Kb, Archivo publicado: oct 2, 2000
    You can build a precision absolute value circuit using two op amps and two precision resistors. If you use an op amp and an IC difference amplifier no user supplied precision resistors or resistor adjustments are required. Circuits shown are suitable for precision split supply operation and for single-supply operation. When used with a rail-to-rail op amp the single supply circuit can approach a
