1 Board overview
The reference board (RFB) is a reference and demonstration board for Infineon's MA12040, MA12040P, MA12070
and MA12070P amplifiers. See the board in Figure 1 with MA12070 mounted.
It contains a variety of digital/analog input, output and set-up/selection features. It also contains one on-board
power supply (5 V buck converter), so only one external power supply (PVDD) is necessary.
