2.3.1 Analog Input and VDD1/AVDD Power

The analog supply voltage can be applied directly to J1.2 (AVDD) with respect to J1.1 (AGND). The analog input can be applied to the double turret connector (VHV1) with respect to AGND. The input voltage range is dependent on the device selected and installed; refer to the device data sheet for the max input voltages allowed.

The details of an input connection are listed in Table 2-2.

CAUTION: Carefully review the selected device data sheet for limitations of the analog input range and make sure the appropriate analog and digital voltages are applied prior to connecting any analog input to the EVM.
