The National Instruments 777796-01 is a PXI Analog Output Module from the PXI-6704 series, designed for versatile analog output capabilities tailored for general-purpose digital I/O applications. This module features a total of 32 analog output channels, divided into 16 voltage and 16 current outputs, along with eight TTL/CMOS digital I/O connections. Each analog output channel provides independent voltage range settings, making the 777796-01 particularly suitable for software-timed voltage and current output applications across various environments, including production testing, laboratory experiments, and industrial process control.

The module is equipped to generate a diverse array of signal outputs necessary for driving devices such as LEDs, optically isolated solid-state relays, and electromechanical relays, as well as providing excitation for precise transducers. With a resolution of 16 bits, it achieves transfer characteristics of ±1 LSB for both Differential Nonlinearity (DNL) and Integral Nonlinearity (INL), ensuring precision and monotonic behavior for output signals. For voltage outputs, the 777796-01 supports a voltage range of ±10.1 V with a DC output coupling and a maximum output impedance of 0.1 Ω, capable of delivering up to ±10 mA of current while handling load capacitances of up to 10,000 pF. The current output offers a range of 0.1 to 20.2 mA and operates as a source without the need for external excitation, featuring a minimum output impedance of 1 GΩ and supporting outputs up to 10 V with an absolute accuracy of ±2 μA and a noise level of 1 μArms across DC to 1 MHz.

The integrated digital I/O section includes eight channels with a power-on default set to input (high impedance). The 777796-01 module can be easily programmed with several software environments, including LabVIEW, LabWindows/CVI, ComponentWorks, and VirtualBench, making it a versatile addition to the National Instruments platform for applications demanding precision and reliability. Recommended warm-up time for optimal performance is approximately 15 minutes.
