National Instruments 777306-01

The National Instruments 777306-01 Analog Output Device is an integral component of the PCI-6704 model series, designed for high-precision applications requiring a robust static analog output solution. This 32-channel device features 16 voltage output channels and 16 current output channels, making it well-suited for software-timed voltage and current output tasks. In addition to its analog capabilities, the device incorporates eight digital I/O lines, enhancing its versatility across various applications, including industrial process control, laboratory experimentation, and production testing.

The 777306-01 operates effectively as a DC setpoint tool within PCI and PXI systems, generating experimental stimuli and seamlessly interfacing with a broad range of signals, such as precision transducers and electromechanical relays. It includes two calibration channels for voltage adjustments and two for current modifications, ensuring sustained accuracy and reliability through continuous self-calibration. The device architecture employs a time-division multiplexed design with a 16-bit Enhanced R-2R digital-to-analog converter (DAC), ensuring stable output through a dedicated track-and-hold circuit for each channel.

With user-definable power-on states, this device delivers a voltage output range of ±10.1 V and current output capabilities ranging from 0.1 to 20.2 mA, all without the need for external excitation sources. The output compliance is defined from 0 to 10 V, providing flexibility for a variety of applications. Calibration settings are stored in Flash memory during factory calibration, enabling efficient compensatory adjustments for onboard reference drift. Overall, the National Instruments 777306-01 is engineered for reliability and precision in demanding analog output scenarios.
