About
One or more 8-Channel Analogue Multiplexer Modules are normally used in conjunction with the J-Testr ADC/DAC peripheral card to extend the number of ADC and/or DAC channels available in the test system. For example only 8 modules are required to extend the standard 8 differential inputs of the ADC to 64 differential inputs or 128 single ended inputs. More than 8 modules can be added in additional levels of multiplexing to almost endlessly extend the number of channels available. In a similar manner to the ADC the 8-Channel Analogue Multiplexer Modules can be used to extend the DAC channels.
The compact dimensions (22mm x 35mm) of the module means it can be used very close to the UUT, for example on Connection Cards, or on the J-Testr Interposer. The connector pin-out is designed to easily route into the ADC/DAC peripheral card with minimal effort and maximum efficiency.

Locating the multiplexer close to the UUT can significantly reduce the cabling requirements, saving both cost and time, whilst simultaneously giving improved signal integrity. With the fully integrated -55V to +55V protection the user can be confident that the module is robustly protected against UUT faults.
The module is 100% compatible with the J-Testr ADC/DAC peripheral card’s external multiplexer scanning mechanism. |
