AVAILABILITY NOTE: According to e2v the ADC & DMUX is not recommended for new designs as it is not being manufactured anymore due to the manufacturing technology being obsolete (i.e. no new devices can be manufactured). Devices are still available from existing stocks, but at some point these devices will become obsolete as the stocks are depleted.
