What the HX720 family does
The HX720 is a 24-bit analog-to-digital converter designed for high-precision electronic scales. It spans variants with commercial and industrial temperature ranges. Key parameters include a 17-bit noise-free resolution at 10 Hz, a 128x internal amplifier gain, and a built-in 3.3V low-noise voltage regulator. The device features an integrated battery voltage measurement channel and a clock oscillator requiring no external components. It typically replaces external regulators on scale motherboards, driving sensors, displays, and microcontrollers while simplifying system design and reducing overall cost.
