Description

Operational amplifier is designed to handle strain beams. The system is supplied with the voltage from 2.6 V to 5.5 V, communicates via a two-wire bus: the data line and a clock line.

 

Connection

The strain beams are supported through the so-called Wheatstone bridge, i.e. wires connected in the following way:

  • E+ (Excitation+)- positive excitation or VCC (power supply)
  • E- (Excitation-) - negative excitation or GND (ground)
  • A- / A+ -- positive strengthening, a positive signal or a positive output
  • B- / B+- the negative strengthening, the negative signal or a negative output

 

 

For communication with the microcontroller, e.g. Arduino, the system uses two lines: CLK and DAT.

 

Pin Description
VCC The supply voltage is from 2.6 V to 5.5 V.
DAT Data line of the communication bus.
CLK Clock line of the communication bus.
GND The ground of the system.
