A guide to selecting an operational amplifier for optimum noise performance is presented.
low noise amplifier
Eight years ago, George Erdi wrote a very useful Design Note (Chapter 457) that presented information to aid in the selection of op amps for optimum noise performance, in both graphical and tabular form. This chapter is an update of that Design Note. It covers new low noise op amps as well as some high speed op amps. Although a great deal has changed in eight years, especially in electronics, noise is still a critical issue in op amp circuit design and the LT1028 is still the lowest noise op amp for ...
