The Advme2608 is a 16-bit resolution A/D converter VME board with 64 singled-ended and 32 differential input channels.
Jumper switch can be used to set the input range for all channels at once to one of the following ranges: ±10V, 0 to 5V or 0 to 10V. Operates from a single +5V power supply by VME bus
Isolation:
Input channels are isolated from the VME bus.
A/D Conversion
Internal state machine automatically performs A/D conversion.
Built-in pacer clock allow A/D conversion to be periodically performed.
Built-in 512-word FIFO is provided.
Other Features
Interrupt can be issued after scanning is completed.
LED lamp indicates A/D conversion in progress and bus access.
C-language sample program is provided.
Device driver for VxWorks is available as an option.
