Description
The HX720 is a precision 24-bit analogto-digital converter (ADC) with on-chip 3.3V output power supply regulator that can be used directly as the power supply for the ADC and MCU simultaneously. It’s designed for weigh scales and industrial control applications to interface directly with a bridge sensor.
