1. How do pre-biased BJTs differ from standard BJTs?
Pre-biased BJTs include integrated resistors, reducing the need for external components. This saves PCB space and simplifies the design process compared to standard BJTs.
-
2. What are typical configurations available in pre-biased arrays?
They come in various configurations, such as dual NPN, dual PNP, or a mix of NPN and PNP transistors in a single package.
-
3. What are the advantages of using pre-biased BJTs in designs?
Advantages include reduced design complexity, space-saving on PCBs, lower production costs, and increased reliability due to fewer external components.
-
4. How do built-in resistors affect circuit performance?
The integrated resistors ensure consistent biasing, reducing variations in performance and simplifying design. However, they may slightly limit flexibility in tailoring biasing configurations.
