- Low Power Input and Reference Driver Circuit for ADS8318 and ADS8319PDF, 1.5 Mb, Archivo publicado: jun 24, 2009
The one size fits all approach to operational amplifiers is not effective. Every application has its own specific requirements that must be fulfilled. Appropriate selection of the op amp that drives an analog-to-digital converter (ADC) in a low-power application is a critical step. Most available low-power op amps trade off low-power features with other parameters such as bandwidth, settling t - Voltage Feedback vs. Current Feedback Op AmpsPDF, 93 Kb, Archivo publicado: nov 30, 1998
This application report contrasts and compares the characteristics and capabilities of voltage and current feedback operational amplifiers. The report also points out the many similarities between the two versions. - Designing for low distortion with high-speed op ampsPDF, 277 Kb, Archivo publicado: marzo 2, 2005
- 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
