The DNR-AO-332-828 is a high density, high-precision, 28-channel analog voltage output layer available in the DNR/DNF form factors. Similar in functionality to UEI’s popular DNR-AO-332, the board offers 4 fewer channels than the standard 332, but provides 4 additional ground pins on the I/O connector. This allows users to keep the output cables in signal/ground pairs. The board offers full 16-bit resolution and guarantees monotonicity over the entire operating temperature range. Utilizing an innovative per-channel digital offset and gain calibration, initial gain and offset errors are limited to ±450 μV and ±305 μV respectively. Each DNR-AO-332-828 channel provides an output range of ±10 V and is capable of driving ±10 mA. For applications requiring higher output current, please refer to the DNR-AO-308-350 layer.
All 28 channels may be configured to update simultaneously, or theymay be updated one at a time as data is written. A 1024 sample FIFOon each channel allows each D/A to be updated at 10 kHz without dataloss. Double buffering the outputs combined with the use of low glitchD/As make the DNR-AO-332-828 an ideal solution for generating lowfrequency wave forms or providing highly accurate switched stimulus.The board also offers a digital input bit which may be used as a trigger oras a general purpose input. A digital output bit is also provided.
Software included with the DNR-AO-332-828 provides a comprehensive, yet easy-to-use API that supports all popular Windows programming languages as well as supporting programmers using Linux and most real-time operating systems including QNX, RTX, VXworks and more. Finally, the UEIDAQ Framework supplies complete support for those creating applications in data acquisition software packages such as LabVIEW, MATLAB/Simulink or any application which supports ActiveX or OPC servers.
