Differential signaling has been commonly used in audio, data transmission, and telephone systems for many years because of its inherent resistance to external noise sources. Today, differential signaling is becoming popular in high-speed data acquisition, where the ADC’s inputs are differential and a differential amplifier is needed to properly drive them.Two other advantages of di - High-Voltage Signal Conditioning for Differential ADCsPDF, 125 Kb, Archivo publicado: jun 14, 2004
Analog designers are frequently required to convert high-voltage signals to levels acceptable to low-voltage data converters with differential inputs. This paper describes solutions for this common task using modern amplifiers and typical power supplies. Three examples of conditioning В±10V bipolar signals for low-voltage analog-to-digital converters (ADCs) are shown: a single-supply design, - Noise Analysis for High Speed Op Amps (Rev. A)PDF, 256 Kb, Revisión: A, Archivo publicado: enero 17, 2005
As system bandwidths have increased an accurate estimate of the noise contribution for each element in the signal channel has become increasingly important. Many designers are not however particularly comfortable with the calculations required to predict the total noise for an op amp or in the conversions between the different descriptions of noise. Considerable inconsistency between manufactu
