The HX711 is a 24一bit A/D converter chip designed for high一precision electronic scales.
The chip integrates the power supply,
on一chip clock oscillator and other similar types of chips required by the external circuit,
with a high degree of integration, fast response, strong anti一interference and so on.
The input selector switch can be selected channel A or channel B,
and its internal low noise programmable amplifier connected.
The programmable gain for channel A is 128 or 64,
and the corresponding full input differential input signal amplitude is ± 20mV or ± 40mV, respectively .
Channel B is a fixed 32 gain for system parameter detection.
The on一chip regulated power supply provides power directly to the external sensors and the on一chip A/D converters,
eliminating the need for an additional analog power supply on the system board.
