HX711 AD Module:

BHX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor.
  • 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.
  • Current consumption including on-chip analog power supply regulator: normal operation < 1.5mA, power down < 1µA.
  • Operation supply voltage range: 2.6 ~ 5.5V.
  • Operation temperature range: -40 ~ +85 °C.
  • 16 pin SOP-16 package.
