Notas de aplicación
- Making the Most of a Low-Power, High-Speed Operational AmplifierPDF, 221 Kb, Archivo publicado: nov 22, 2009
High-speed, high-performance operational amplifiers tend to be associated with high power dissipation. This application note compares the relative performance of several low-power, high-speed operational amplifiers and describes trade-offs to balance performance with low quiescent power dissipation. - 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
