HX711 is a 24-bit analog to digital converter (ADC) IC. It as built-in a preamplifier that is used to amplify low voltage signals. HX711 chip takes voltage signals as an input and provides digital values.The preamplifier handles low voltages. It has an on-chip power supply regulator that provides analog power due to which you don’t need an external supply regulator. You can directly interface with a bridge sensor. This chip has two analog channels such as A and B. We can program channel ‘A’ gain either 128 or 64. On the other hand, channel B has constant gain of 32.
