4.1 Analog Input and VDD1 Power: J3 and J1

The analog input voltage to the EVM 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 AMC1400 or input to the AMC1411 (pin 2)
J3.2 INN/SHTDN Analog negative input to the AMC1400 or SHTDN to the AMC1411 (pin 3)
J3.3 GND1 Connection to the GND1 terminal (pin 4)

The isolated power input to the EVM printed circuit board (PCB) can be applied directly to J1 pins 1 and 2. Table 4-2 lists the details of J1.

Table 4-2 J1: VDD1 Power
Pin Number Signal Description
J1.1 VDD1 Connection to the VDD1 terminal (pin 1)
J1.2 GND1 Connection to the GND1 terminal (pin 4)
CAUTION: Carefully review the AMC1400 data sheet or AMC1411 data sheet for the limitations of the analog input range, and ensure that 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.
