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 Ratings†
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 ?

Regards
James

Arduino 1.0 compatible library is available. http://code.google.com/p/neuroelec/downloads/detail?name=mcp4728_library_v1.3_for_Arduino_1.0.zip
