VT2832
Switch Matrix Module
The Switch Matrix Module VT2832 allows arbitrary switching of currents in a matrix with eight columns and four rows. This can be used for example to connect different channels one by one to a measurement device.
Four additional channels can be switched directly which also leads to overall eight individually switchable channels. By the exclusive use of semiconductor switch elements, the number of switching cycles is practically unlimited.
Characteristics
Functions for Each Column
- In each of the eight columns, the overall current and the voltage against AGND can be measured.
- In addition to the individual switching of single matrix nodes, each column can be switched in PWM mode or with an encoding bitstream.
- With this feature, for example periodic switching operations or bouncing contact simulations can be generated.
