The National Instruments 782878-01 PXI Analog Output Module is a high-performance device from the PXIe-4322 family, designed for precision in dynamic voltage and current outputs. This isolated analog output module features eight channels to deliver synchronous outputs with a 16-bit R-2R digital-to-analog converter (DAC) ensuring 16-bit monotonicity. It boasts exceptional accuracy with an integral nonlinearity (INL) of ±4 LSBs and a differential nonlinearity (DNL) of ±1 LSB. The output voltage range extends from ±16 V to a maximum of ±16.83 V, with a current drive capability of ±20 mA per channel, allowing operation in voltage mode. The module excels in low noise performance, specifying 30 μVrms in the 10 Hz to 1 kHz bandwidth, 250 μVrms in the 10 Hz to 300 kHz bandwidth, and up to 500 μVrms in the 10 Hz to 20 MHz bandwidth. The output impedance is maintained at 25 mΩ, providing robust crosstalk characteristics at -100 dB (channel-to-channel at 10 kHz) and a slew rate of ±10 V/μs. Ideal for demanding applications such as automotive testing, the device can sink and source current across all four quadrants of current mode. For safe and reliable operation, the power-on output state defaults to 0 V in voltage mode and 0 mA in current mode. In terms of synchronization, the module supports multiple output timing signals with software-selectable polarity, including Start Trigger, Pause Trigger, Sample Clock, and Derived Timebases and Clocks, interfacing with PXI_TRIG<0..7> and PXIe_DSTARC. It complies with specification rev. 1.0, uses an x1 PXI Express peripheral module form factor, and is compatible with PXI Express hybrid slots or x1 and x4 PXI Express slots. Additionally, it features one DMA channel available for analog input processing. The 782878-01 is a reliable solution for those requiring high precision in their control and automation systems.
