HX711 Description

Short technical summary and product information.

The AVIA HX711 is a precision 24-bit Analog-to-Digital Converter (ADC) based on Avia Semiconductor's patented technology. It is specifically designed for weigh scales and industrial control applications, enabling direct interface with bridge sensors.

The HX711 features two selectable differential input channels, each feeding into a low-noise programmable gain amplifier (PGA). Channel A offers programmable gains of 128 or 64, while Channel B has a fixed gain of 32. The device includes an on-chip power supply regulator, simplifying the design by eliminating the need for an external regulator for the ADC and sensor analog power. The clock input is flexible, supporting external sources, crystals, or an on-chip oscillator that requires no external components.

Key features include selectable output data rates of 10SPS or 80SPS, simultaneous 50 and 60Hz supply rejection, and simple digital control via a serial interface. The HX711 operates within a supply voltage range of 2.6V to 5.5V and a temperature range of -40°C to +85°C. It is housed in a 16-pin SOP-16 package.

This ADC is ideal for applications such as weigh scales and industrial process control where accurate analog-to-digital conversion of bridge sensor signals is required.
