[ts-7000] Re: EP9302 - ADC Sample rate on the TS-7300? Help!!

["lyy_henry" <>]

Hi Guys:

Help-!!!

I am a bit confused by what it said about the ADC on the TS-7300
board. on p38(Ts-7300 manual), it said:
''The cirrus A/D converter can do a maximum of 925 samples per second,
and requires a settling time of 2 milliseconds''
It means to me that, the ADC on EP9302 could only samples 925 p/s at
the most. is it right?
However, according to the EP9302 Data sheet on p32, We could set the
Maximum sample rate to 3750 samples p/s with 500 microseconds settling
time, as long as we set the ADIV ( bit 16 in the KeyTchClkDiv register
) to 0. 1 is 925.

For what I am trying to do, I need at least the 3750 samples p/s in
able to do some voice/sound recognition stuff.
If the sampling rate as it said on the Ts-7300 manual, it is no use at
all, I do not think, we could do much with 925 p/s with 2 milliseconds
settling time.


Does anyone has any experience regarding to my problem or concern?

Thanks guys.
