There are no Philips microcontrollers any more. They are all NXP now. From the NXP, you can use either 8-bit LPC900 devices LPC935 and LPC936 have 8 ADC inputs each of of the LPC2000 series.
The LPC211x and LPC212x have 8 analog inputs, the LPC2138 has up to 16, LPC2148 has 14, LPC2368 has 6 ...... and so on.
Some information on the LPC2000 based devices can be found here: http://www.lpc2000.com
