Description

Operational amplifier is designed to handle strain beams. The system is supplied with the voltage from 2.7 V to 5.0 V, communicates via a two-wire system 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:

  • Red (RED)-  positive excitation or VCC (power)
  • Black (BLK)- negative excitation or GND (ground)
  • White (WHT)- positive amplification, a positive signal or a positive output
  • Green (GRN)- the negative amplification, the signal is negative or the output is negative
  • Yellow (YLW)- grounding, optional input enables to reduce electromagnetic interference

 

 

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