... In summary, the LT1028/LT1128 are the optimum ampli- fiers for noise performance, provided that the source resistance is kept low. The following table depicts which op amp manufactured by Linear Technology should be used to minimize noise, as the source resistance is in- creased beyond the LT1028/LT1128’s level of usefulness. ...
