4.1 Analog Input and VDD1 Power: J3 and J1

The analog input voltage to the AMC1350EVM or AMC1351EVM can be applied directly to J3 pin 1.

Table 4-1 lists the details of J3.

Table 4-1 J3: Analog Input
Pin Number Signal Description
J3.1 INP/IN Analog positive input to the AMC1350 or input to the AMC1351 (pin 2)
J3.2 INN/GND1 Analog negative input to the AMC1350 or GND1 to the AMC1351 (pin 3)
J3.3 GND1 Connection to the AMC1350 or AMC1351 GND1 terminal (pin 4)

The isolated power input to the AMC1350EVM or AMC1351EVM printed circuit board (PCB) can be applied directly to J2 pins 1 and 2. Table 4-2 lists the details of J2.

Table 4-2 J2: VDD1 Power
Pin Number Signal Description
J2.1 VDD1 Connection to the AMC1350 or AMC1351 VDD1 terminal (pin 1).
J2.2 GND1 Connection to GND1. Tie this pin to the AMC1350 or AMC1351 GND1 terminal (pin 4).
CAUTION: Carefully review the AMC1350 data sheet or AMC1351 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. The board is not certified for high-voltage operation.
