Digilent PCI-DDA04/12 Analog Output Board

The PCI-DDA04/12 is an Analog Output Board designed for data acquisition. Equipped with 4 analog output channels, this device was originally manufactured by Measurement Computing, a company which has since been acquired by Digilent (a National Instruments (NI) company). The PCI-DDA04/12 features an AD7837B Digital-to-Analog converter type that boasts 12 bits of resolution, allowing for precise control.

The power consumption of the PCI-DDA04/12 differs depending on the power rail that is used. An operating power rail of +5V typically draws in a current of 1.5A with a maximum of 2.4A max, while a power rail of +12V draws a typical current of 12 mA with a max of 24 mA. Finally, a power rail of -12V has a current draw that is 8 mA typically and 12 mA at maximum.

The PCI-DDA04/12’s analog output throughput is PC dependent, and it features a slew rate of 5V/µs. When it comes to the Digital Input/Output specifications of the device, it has 48 I/O channels. Each bank is configurable, easily programmed as either input or output. The output for the PCI-DDA04/12 ranges from a low of 0.5V to a high of 2.4V, while the input of the board ranging from a low of 0.8V to a high of 2.0V.

Built to withstand a wide range of environmental conditions, the PCI-DDA04/12 is designed to be operated in temperatures ranging from 0 to 70°C. When it is not being used, the analog output board can be safely stored in an even wider range of temperatures, spanning from −40 to 100°C. For both operating and storage conditions, the PCI-DDA04/12 can withstand a noncondensing humidity range of 0 to 90%.
