The ISL73141SEHFNEV1Z board evaluates the operation of the Renesas ISL73141SEH radiation hardened 14-Bit 1000ksps/750kps SAR ADC. This evaluation board is intended to be used with the RHADC-FMCEV1Z data capture board.
The ISL73141SEH device on the evaluation board supports operation of the ISL73141SEH with AVCC set to either 5V or 3.3V. DVCC can be set to 2.5V or 3.3V, but the default setting is 2.5V. The reference voltage to the ADC can be set to 3.0V or 4.096V. Setting the reference voltage to 4.096V is only valid for the 5V version of the ISL73141SEH. The I/O voltage of the CPLD can be set to 2.5V or 3.3V operation as well, but should be matched to the DVCC setting. The supply voltage for the CPLD is set to 1.8V. The supply voltages to the analog input amplifier circuit is set to +7.5/-4.5V. These voltages are all derived from the ±10V supply inputs to the board.
To properly operate the ISL73141SEH board and the RHADC-FMCEV1Z board the following is required:
