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.
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
