General Description

Based on Avia Semiconductor’s patented technology, HX711 is a precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor.

The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA).

Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of ±20mV or ±40mV respectively, when a 5V supply is connected to AVDD analog power supply pin.

Key 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.
