Description
The product with the part number 776572-40 falls under the SCXI & Legacy category, identified as model SCXI-1140. It is described as an 8-Ch. Simultaneously Sampling Differential Amplifier, designed to cater to various signal amplification needs with its 8 channels. This model is compatible with NI-DAQmx, NB Series, LabVIEW for Macintosh, and NI-DAQ for Macintosh, ensuring a wide range of application support.
It features a maximum output voltage of ±10 V and a channel output slew rate of 15 V/µsec, indicating its capability to handle rapid changes in signal amplitude. Additionally, the input noise spectral density is rated at 12 nV/√Hz, while the output noise spectral density stands at 75 nV/√Hz, highlighting the amplifier’s efficiency in minimizing noise in signal processing.
For protection, it incorporates a 1 kΩ resistor in series as part of its input protection mechanism. The SCXI-1140 supports single module parallel and multiplexed scanning modes, enhancing its flexibility in data acquisition and instrumentation setups. It includes a read-only ID register (4-byte) and a write-only Configuration register (32-bit), facilitating device identification and configuration management.
The End of Life Status for this product has been announced by National Instruments but it remains available at Apex Waves, offering a valuable resource for users requiring this specific model for their applications.
