1B32 application circuit with multiple pressure sensor shown in Fig. Excitation power through AD542, after TIP32 then drive multiple bridge sensors. AD542 is a Bi-FET as the in
put stage of the operational amplifier, where the act as a buffer. TIP31 NPN epitaxial type power transistors, the maximum reverse voltage of 45V, maximum collector current of 3A, the maximum power consumption of 40W. The circuit in the temperature range of -25 ~ + 80 to provide + 10V, 300mA source of excitation. The 1B32 of 333.3 GAIN grounded, the gain is set as 333.3 times.
