The Advme2706 is a 16-bit resolution, VME bus compliant board with a 16-channel D/A converter.
A ±10V output range can be expanded to ±12V by installing a resistor for output range expansion.
All channels are equipped with an independent trimmer for gain and offset adjustment, allowing highly accurate adjustment for each channel.
Isolation
Output channels are isolated from the VME bus.
It is equipped with an output short-circuit protection function.
Other Features
Operates from a single +5V power supply by VME bus.
When the power is turned on and when reset is performed, the output voltage is forced to 0V.
LED lamp indicates bus access.
C-language sample program is provided.
Device driver for VxWorks® available as an option.
