J2 provides access to the +5 VA for the V DD 2 supply. All power to the board should be sourced from a
well-regulated, linear supply that has current limiting capabilities. Power is to be applied through J2.
Table 1 describes the pinout for J2.

For standalone operation, power sources can also be applied via a mating connector to J2, and the digital
output data stream can be wired directly to an FPGA or other digital filter module for further processing.
Refer to Figure 2 or the schematic appended to the end of this document for additional details.

EVM Set-up and Operation
This section describes the general operation of the AMC1204EVM.
Isolated Power and Analog Inputs: J1 and J4
The isolated power input to the AMC1204EVM printed circuit board (PCB) can be applied directly to J1,
pins 1 and 2. Table 2 lists the details of J1.

The analog input to the AMC1204EVM PCB can be applied directly to J4 pins 1 and 2. Table 3 lists the
details of J4.
CAUTION
Carefully review the AMC1204 product data sheet for the limitations of the
analog input range, and ensure that the appropriate analog/digital voltages are
applied before connecting any analog input to the EVM.
