A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...
Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...
Texas Instruments' Burr-Brown Division recently released the single OPA1641, dual OPA1642, and quad OPA1644 operational amplifiers, which feature a JFET input stage. The parts operate with ±2.25 to ...
Native SPICE elements that accurately replicate an op amp’s real-world behavior were nonexistent. A transconductance sourcing current from the rails and transitioning to a resistive state as the ...
