This module uses 24 high precision A/D converter chip hx711. It is a specially designed for the high precision electronic scale design・with two analog input channel・the internal integration of 128 times the programmable gain amplifier. Theinput circuit can be configured to provide a bridge type pressure bridge (such as pressure・weighing sensor mode)・is of high precision・low cost is an ideal sampling front-end module.
Features:
*Two selectable differential input channels
*On-chip active low noise PGA with selectable gain of 32・64 and 128
*On-chip power supply regulator for load-cell and ADC analog power supply
*On-chip oscillator requiring no external component with optional external crystal
*On-chip power-on-reset
*Simple digital control and serial interface: pin-driven controls・no programming needed
*Selectable 10SPS or 80SPS output data rate
*Simultaneous 50 and 60Hz supply rejection
