BJT Test Board

Figure 3-1 shows the three possible configurations for remote temperature sensing with BJTs using the TMP468EVM. The transistors included in these tests were used in the NPN or PNP diode-connected configurations, and Figure 3-2 shows the test board designed to connect eight of each BJT in Table 2-1 to the TMP468EVM, which can measure temperatures of up to eight remote transistors at once.
