CY8C29666 ADINC14 with 2.5V external ref can't read full count
I try to read a 0 to 2.5V with the ADCINC14, i use the REFMUX for read 8 port, and I use the external ref (P2, P2).
Analog Power : SC On/Ref High
Ref Mux : P2+/-P2
VDD : 5V
P2 : 0V
P2 : to a ref 2.5V
Problem; can't read more than ~15818 counts...
2^14 = 16384
ref 2.5V/16384 = 152.588uV
15818 * 152.588uV = 2.414V <- this is my problem, if the input is 2.5V or greater never read more than this.
Thanks for reading and helping me :)
