Does pic 18f4450 have internal 12-bits ADC

[Keinstein]

Hi guys,
I've looked at the data sheets for both the pic 16f877A and the pic 18f4450 for an on-board 12-bits adc and couldn't see it mentioned anywhere except the 10-bits adc. Do they have 12-bits adc?
And if it has then is the following definition right?

#include <18F4450.h>
#device adc=12

Kind regards,
S.Keinstein

Nope 10bit
Some 30F have 12bit. Microchip has a parametric search for 12bit A/D devices.

No, only 10 bit available.

thank you guys

Microchip have removed their search for this. 18F2423 and 18F2458 families are 12bit if you are looking for this.

How about 18F4450 family?

David, how about 18F4450 family since it seems to be the latest version compared to 8F2423 and 18F2458 families?
Kind regards,
S.K

My datasheet also says 10bit AD for the 18F4450. Why do you want 12bit anyway? My limited experience with 12bits is that they seem trickier to implement and perhaps there are workarounds using 10bit.

You could also use one of Microchips 12bit ADC chips with SPI interface like the MCP3201, MCP3202. Or even 13bit; MCP3301, MCP3302, etc.
