4 EVM Operation
The following section describes the general operation of the AMC1311EVM.
4.1 Isolated Power and Analog Inputs: J1 and J4
The analog input voltage to the AMC1311EVM can be applied directly to J1 pins 1 and 2.
Table 1 lists the details of J1.
Table 1. J1 – Analog Input
Pin Number Signal Description
J1.1 VINP Analog input to the AMC1311.
J1.2 GND1 Ground connection.
J1.3 ShutDown Optional input to drive the shutdown pin from an external source.
The isolated power input to the AMC1311EVM printed circuit board (PCB) can be applied directly to J4
pins 1 and 2.
Table 2 lists the details of J4.
Table 2. J4 - VDD1 Power
Pin Number Signal Description
J4.1 VDD1 Connection to the AMC1311 VDD1 terminal (pin 1) with SH-J5 shorting pins 2-3 on J5.
J4.2 GND1 Connection to the AMC1311 GND1 terminal (pin 4).
CAUTION
Carefully review the AMC1311 product data sheet for the limitations of the
analog input range, and ensure that the appropriate analog/digital voltages are
applied prior to connecting any analog input to the EVM. The transformer on
the evaluation module is rated to 2500 Vrms, but the board is not certified for
high voltage operation.
4.2 User Power and Analog Outputs: J2, J3 and J6
The differential analog output voltage from the AMC1311EVM printed circuit board is applied directly to J2
pins 1 and 2.
Table 3 lists the details of J2.
Table 3. J2 – Differential Analog Output
Pin Number Signal Description
J2.1 VOUTN Non-inverting analog output from the AMC1311 (pin 6).
J2.2 VOUTP Inverting output from the AMC1311 (pin 7).
The VDD2 power input to the AMC1311EVM printed circuit board can be applied directly to J3 pins 1 and
2.
Table 4 lists the details of J3.
Table 4. J3 – VDD2 Power
Pin Number Signal Description
J3.1 VDD2 Connection to the AMC1311 VDD2 terminal (pin 8).
J3.2 GND2 Connection to the AMC1311 GND2 terminal (pin 5).
The single-ended analog output voltage from the AMC1311EVM printed circuit board is applied directly to
J6 pin 1 referenced to pin 2.
Table 5 lists the details of J6.
