Chapter 23. Circuit Board Layout Techniques
23.1. General Considerations
Prior discussions focused on how to design op amp circuitry, how to use ICs, and the use of associated passive components. One additional circuit component must be considered for the design to be a success—the printed circuit board (PCB) on which the circuit is to be located.
23.1.1. The PCB Is a Component of the Op Amp Design
Op amp circuitry is analog circuitry and very different from digital circuitry. It must be partitioned in its own section of the board, using special layout techniques.
Printed circuit board effects become most apparent in high speed analog circuits, but common mistakes described in this chapter can even affect the performance of audio circuits. ...
