The ISL71148MNZEV1Z board evaluates the operation of the ISL71148M radiation tolerant 8-channel high-precision 14-bit, 900ksps/480ksps SAR ADC. The evaluation board is used with the RHADC-FMCEV1Z data capture board.

The ISL71148M device on the evaluation board supports the operation of the ISL71148M with AV_CC set to 5V. DV_CC can be set to 2.5V or 3.3V (default setting is 2.5V). The reference voltage to the ADC is set to 2.5V. The digital I/O voltage of the complex programmable logic device (CPLD) can also be set to 2.5V or 3.3V operational, but it matches the DV_CC setting of the ISL71148M. By default, the supply voltage for the CPLD is also connected to the digital I/O voltage. The supply voltages to the analog input amplifier circuit are set to +7.5V/-4.5V. These voltages are all derived from the ±10V supply inputs to the board.
