Buffer Op Amp to ADC Circuit Collection

December 1, 2014 Leave a comment Go to comments

In most cases, analog to digital converters (ADCs) also require a buffer amp. The choice of buffer op amp, and how to connect it to the ADC, are some of the most challenging tasks facing experienced analog designers—much more so with digital designers who are often assigned the task. This document presents designers with a library of interface techniques, but leaves the choice of op amp to other documents. In general, however, op amp specifications that are important to the system design should be much better than the equivalent specification of the ADC Otherwise, money is wasted on an expensive ADC. A good buffer op amp is usually an order of magnitude less expensive than the ADC, and economizing on a buffer op amp is a poor decision.
