I'm not sure if the afirmation about technology is completely true, but in my opinion the Microchip analog parts have characteristics slighty below (on some parts claiming equaly with) the competitors. It rising up only because prices. For example a lot of OA produced by Microchip may have a larger offset interval than the same lot tested from NS or TI.
