... N where R is the total input source resistance. S This equation is plotted for the AD8597/AD8599 in Figure 58. Because optimum dc performance is obtained with matched source resistances, this case is considered even though it is clear from Equation 1 that eliminating the balancing source resistance lowers the total noise by reducing the total very low source resistance (R amplifier dominates ...

... AD8597/AD8599 The AD8597/AD8599 are the optimum choice for low noise performance if the source resistance is kept < 1 kΩ. At higher values of source resistance, optimum performance with respect to only noise is obtained with other amplifiers from Analog Devices. Both voltage noise and current noise need to be consi- dered ...
