Q: The MAX2090 application circuit includes components for the ALC loop, but no information on how to choose components to tune the loop response. How do I do this?
A: The MAX2090 datasheet Table 2 provides the recommended ALC loop components (R5, R7, C8 and C9) used in the Typical Application Circuit. Maxim recommends using these values which have been used for characterization of the product. Customers may change these values for a particular application, and the the attached spreadsheet provides an ALC loop compensation calculator. This is the only guide we have for modifying the compensation values.
