3 Digital Interface
The AMC1305EVM is designed for use with digital filters (such as the ΔΣ filter module in the
TMS320F28377D or the AMC1210). The power, clock input, and modulator data output of the AMC1305
device are routed to the two-wire screw terminals at J1, J3, and J4, as
Figure 2 shows.
Figure 2. Power, Clock Input, and Digital Data Output
Note that component R2 in Figure 2 is marked as DNP (do not populate) because Figure 2 corresponds to
an AMC1305EVM populated with a CMOS variant of the AMC1305. Refer to Table 1 for additional details
about the analog input ranges and interfaces available in the AMC1305 family.
4 Power Supplies
Power for the controller side of the AMC1305 device is supplied through the two-wire screw terminal at J1.
The user has two options to provide power for the high side of the AMC1305 device. One option is to
supply the high side of the AMC1305 through the two-wire screw terminal at J5; to accomplish that, the
user must set jumper JP1 to the position labeled
Ext ; see Figure 3 .
