About the Board
AD12-16(PCI)E, AD12-16U(PCI)E and AD16-16(PCI)E are PCI-compliant interface boards that
convert analog input signals to digital equivalents (performing analog-to-digital conversion).
< AD12-16(PCI)E > is the general-purpose type that can perform A-D conversion at a conversion speed
of 10
µ
sec per channel and a resolution of 12-bit.
< AD12-16U(PCI)E > is the high-speed type that can perform A-D conversion at a conversion speed of
1
µ
sec per channel and a resolution of 12-bit.
< AD16-16(PCI)E > is the high-precision type that can perform A-D conversion at a conversion speed
of 10
µ
sec per channel and a resolution of 16-bit.
Using the bundled driver library [API-PAC(W32)], you can create Windows application software for
this board in your favorite programming language supporting Win32 API functions, such as Visual
Basic or Visual C/C++.
Features
Sixteen single-ended channels and eight differential channels (Analog input function)
Either board allows the single-ended or differential input mode to be selected with on-board jumpers.
The order of channels subject to signal conversion can be preset in the dedicated register. Using an
optional unit, the board can increase the maximum number of input channels (up to 32 channels) and
perform simultaneous sampling.
On-board buffer memory (Analog input function)
The board has buffer memory available as a FIFO or ring buffer to hold 256 kilobytes of data. This
enables sampling to be executed in the background independently of the processing power of the PC.
Assorted sampling control functions (Analog input function)
The board can control the starting and stopping of sampling not only with software commands but also
by detecting analog signal strength or TTL-level signals. The board offers a choice of sampling clocks
selectable to determine the sampling speed: the internal sampling clock using the on-board clock
generator and the external sampling clock using the digital signal input from an external device.
Analog output function
The board has one channel of analog output function.
Digital input/output function
The board has four digital input and four digital output pins for TTL-level signals, allowing an external
device to be monitored and controlled.
Abundant optional units
Optional units are available for enhancements.
Using optional units enhances board functions and facilitates connections.

“Accessories (Option)”.
