[Gumstix-users] robostix ADC channels

[Ali, I. <Imr...@ds...>]

Greetings!

I was reading a "Beginner's Guide To Accelerometers" at this web address:

http://www.dimensionengineering.com/accelerometers.htm

It mentions: "Both PIC and AVR datasheets specify that for A-D conversion t=
o work properly, the connected device must have an output impedance under 1=
0k=D9. Unfortunately, Analog Devices' analog accelerometers have an output =
impedance of 32k=D9".

Point being, I was considering purchasing an accelerometer breakout which m=
akes use of an Analog Device accelerometer with analog output. Is there any=
 merit in this warning: has anybody actually ever had difficulty feeding an=
alog output directly into a robostix ADC channel?=20

Cheers
