datasheet - http://ww1.microchip.com/downloads/en/DeviceDoc/22187a.pdf -

page 1:
Output Voltage Range:
- Using Internal VREF (2.048V):
0.000V to 2.048V with Gain Setting = 1
0.000V to 4.096V with Gain Setting = 2
- Using External VREF (VDD): 0.000V to VDD


Page 3:
Absolute Maximum Ratingsā€ 
VDD...................................................................................6.5V


So 10V is not possible, you need to add some heavy duty transistor or so... (no electrical guru)

Hi,

Just curious if you are planning to upgrade this library to Arduino 1.0 ?

Hey,

i have a question:

is this libary compatible with Arduino 1.5.6 an Arduino Due?


robtillaart

I had a quick look at the library and I did  not see incompatible code (that is no guarantee BTW ;)

Thanks for the quick reply.

I will test it with the Arduino Due and write my solution here.
