National Instruments NI 6704

The National Instruments NI PXI-6704 (Part Number: 777796-01) is an Analog Output Module, which can be used to create software timed voltage and current output applications. The user can autonomously set the output voltage range on each channel. The PXI-6704 also incorporates eight digital 5 V TTL/CMOS I/O lines.

The NI PXI-6704 has one 16-bit DAC that is time-division multiplexed to make all the output channels. Each channel has a track-and-hold circuit to keep up the channel value between DAC updates. On this model, the DAC is multiplexed to create 16 voltage outputs, 16 current outputs, and four calibration channels.

It has an analog output voltage range of -10.1 V to 10.1 V. The onboard temperature sensor measures the air temperature flowing over the board. This sensor is situated close to the onboard precision voltage reference, which can be influenced by extraordinary temperatures. This sensor has a serial computerized interface.
