hx711 datasheet

The Hx711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scale and industrial control applications. It is specifically designed to interface directly with a bridge sensor, such as a strain gauge, to provide highly accurate weight measurements. Featuring a low-noise programmable amplifier, the Hx711 is capable of reading weigh scale and sensor outputs with high resolution and excellent stability. It offers two differential input channels, allowing for the connection of both the positive and negative bridges of the sensor. This enables the Hx711 to convert changes in pressure, force, or tension into digital values with minimal noise interference. The Hx711 operates with a supply voltage of 2.7V to 5.5V, making it compatible with a wide range of microcontrollers and systems. It also includes a low-current power-down mode, reducing power consumption when not in use. With its compact size and simple SPI communication interface, the Hx711 is an ideal choice for applications requiring accurate weight measurements, such as industrial scales, automated filling machines, and process control systems.
