The PCIe-16AO64C is a precision 16-Bit analog output product that provides 64 simultaneously clocked output channels in a PCIe form factor. Outputs can be clocked at rates up to 500 KSPS per channel, and are supported by a 256K-Sample FIFO data buffer. Both continuous and burst clocking modes are supported, and voltage ranges are software-selectable as ±10V or ±5V; or optionally as 0 to +10V or 0 to +5V. Clocking and triggering rates can be derived from an internal rate generator, or from external clock and trigger sources to support the synchronous operation of multiple boards. When equipped with the optional outputs-disconnect feature, the outputs can be disconnected from the system I/O connector under software control.
Each analog output channel implements an R-2R DAC, which minimizes latency and has no minimum clocking rate. The outputs can be factory-configured for single-ended operation or for 3-wire balanced differential operation.
