Overview

Description

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 AVCC set to 5V. DVCC 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 DVCC 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.
