HX711 Load Cell Amplifier - 24bit ADC for Weigh Scales

The 7Semi HX711 Load Cell Amplifier is a 24-bit analog-to-digital converter (ADC) designed for precise weight measurements in applications like industrial scales and process control. It features two selectable differential input channels, an on-chip low-noise programmable gain amplifier (PGA) with gains of 32, 64, and 128, and supports a simple two-wire interface for easy integration with microcontrollers. The module operates within a supply voltage range of 2.6V to 5.5V and offers selectable output data rates of 10SPS or 80SPS.

• High Accuracy: 24-bit ADC ensures precise weight measurements, crucial for industrial applications.
• Easy Integration: Simple two-wire interface (Clock and Data) compatible with any microcontroller’s GPIO pins.
• Versatile Load Cell Support: Supports a four-wire Wheatstone bridge configuration for load cells with standard color coding.
• Low Power Consumption: Operates efficiently with a voltage range of 2.7V to 5V and a current draw of less than 1.5mA.
• Flexible Output Rates: Select between 10SPS or 80SPS output data rates, with simultaneous 50 and 60Hz supply rejection for stable performance.
• Color-Coded Connections: Clear wiring with standard color codes (Red, Black, White, Green) for effortless setup.
  • Red (Excitation+ or VCC)
  • Black (Excitation- or GND)
  • White (Amplifier-, Signal- or Output-)
  • Green (A+, S+ or O+)
