Hello. I'm looking for someone having practical experience of cascading video amp like NE592 or LM733 in order to get wide bandwidth and huge gain.

berkeman said:With huge gain can come huge noise. What is the application? What are your target specs?
Ravaner said:Hi. I know that for noise and possible oscillations. My target is BW >= 10 MHz, Av >= 10^^6. I already saw with 2 Ic's cascaded, and I just want to know if someone has really tested with 3 or more pcs.
A cascading op amp is a circuit configuration where two or more op amps are connected in series to achieve higher gain or other desired characteristics.
The main benefit of using a cascading op amp is the ability to achieve higher gain than a single op amp can provide. It also allows for improved linearity and reduced output impedance.
Cascading op amps are commonly used in audio amplifiers, signal conditioning circuits, and active filters. They are also used in instrumentation and control systems.
One challenge is ensuring stability, as the overall circuit can become more sensitive to external noise and disturbances. Designing for proper frequency response and avoiding oscillations can also be a challenge.
One way to gain practical experience is to build and test circuits using cascading op amps. You can also study and analyze existing designs, and simulate circuits using software tools. Additionally, attending workshops or joining online communities can provide opportunities to learn from experienced engineers and exchange knowledge with others.
