2.2.1 Theory of Operation

Figure 3-1 shows a simplified schematic of the AFE11612EVM board. All of the AFE pins are accessible through pin headers. There are two 12-pin connectors that provide access to all of the DAC pins, while a single 32-pin header is used to access the ADC channels. Two 12-pin connectors are used for the digital input and output (I/O) pins and the serial interface signal lines. For access to the eight GPIO pins, there are two 8-pin connectors located near the bottom of the board. Four of these pins (connected to the J19 header) are used as remote temperature sensor inputs D1+, D1–, D2+ and D2–. The AFE11612EVM board features two bipolar junction transistors (BJTs); one BJT is connected across D1+ and D1–, and the other BJT is connected across D2+ and D2–.
