When 1832 is used for bridge measurement, the peripheral circuit is very simple, as shown in the figure.
Adjust the driving voltage (@ pin) of the sensor measurement bridge. Its adjustment range is +4 to +10V.
The specific value is determined according to the actual needs of the sensor. The two fixed gain 333.3 and 500 pins ⑩ and ⑩ are active when connected to low level, and the gain of 100~
5000 is continuously adjustable depending on the RF/R of ⑨ and @ pins. The output voltage is ±10V.
