Basically this means many of their analog parts will be good enough for higher voltage (12V, or even +/-15V) operation. Therefore we basically do not use any Microchip analog parts. Telcom (which Microchip acquired) used to produce the best MOSFET drivers, now other companies have caught up. Yes Microchip has about US$100 million analog business. But it will take a long time for them to be a real analog company. Just take note that all the CMOS process Linear Technolog is using is at least 0.6 Micron.
