Description
The product specifications highlight its robustness and versatility in handling a variety of tasks. With Part Numbers including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04, this device caters to a broad range of applications. It supports 16 single-ended or 8 differential Analog Input Channels, offering flexibility in signal acquisition.
The device boasts an ADC Resolution of 18-bits, ensuring high precision in analog to digital conversion. For tasks requiring rapid data acquisition, it provides a Sample Rate of up to 625 kS/s maximum for a single channel and up to 500 kS/s maximum for multiple channels, accommodating both high-speed and multi-channel scenarios.
Concerning safety, the device is designed with Overvoltage Protection of ±25 V when the device is on and ±15 V when off, coupled with an Input Current (Overvoltage) limit of ±25 mA maximum per AI pin. This ensures the device’s resilience against unexpected voltage spikes. Additionally, it has an Input Bias Current of ±100 pA, minimizing error in measurement due to bias.
On the output side, it features 2 Analog Output Channels with a DAC Resolution of 16-bits, providing precise control over output signals. The Update Rate is impressive as well, reaching up to 2.86 MS/s maximum for one output channel and 2.00 MS/s per channel maximum when both are used, ensuring swift response times in output signal generation.
Finally, the device maintains a Timing Accuracy of 50 ppm, which underscores its reliability in timing-sensitive applications. This level of accuracy is essential for applications where timing precision is critical to the success of the operation.
