About HX711

The HX711 is an advanced and highly precise 24-bit analog-to-digital converter (ADC) developed by Avia Semiconductor. It is specifically designed for weight scales and industrial control applications, allowing direct interfacing with a bridge sensor. This ADC utilizes Avia Semiconductor’s patented technology to ensure accurate and reliable conversion of analog signals into digital data.

One of the key features of the HX711 is its Delta-Sigma architecture, which enhances the conversion process and provides high-resolution measurements. With its 24-bit resolution, this ADC can capture even the smallest variations in weight or other analog signals. The HX711 comes in a SOP16 package, making it easy to integrate into various electronic systems.

HX711 has two input channels, enabling simultaneous measurement of multiple sensors or inputs. It offers serial access, facilitating efficient data transfer and communication with microcontrollers or other devices. The HX711 operates within a wide temperature range, from -40°C to 85°C, making it suitable for both indoor and outdoor applications. Additionally, it supports a supply voltage range of 2.6V to 5.5V, ensuring compatibility with different power sources.
