24-bit A/D Converter Module with TM7711
The TM7711 is a 24-bit A/D converter designed exclusively and widely used in high precision weighing systems.
It allows an accurate conversion of the data read by the resistive weight sensors, the Wheatstone bridge configuration reading, amplifying and converting the differential voltage is the most recommended for the purpose.
It only requires a single voltage between 2.6 and 5.5V and has a pure differential input with reference.
Thanks to the two-conductor serial protocol it integrates perfectly with Arduino and MCU.
