Load Cell Adc Ic

Hx711 is a precision 24 bit analog to digital converter adc designed for weigh scales and industrial control applications to interface directly with a bridge sensor load cell strain guages.

Load cell adc ic.

Rs 578 00 433 mhz frequency around 100 meters range built in telescopic antenna keypad slide type protection cover ev1527 chip based protocol. It consists of an ad7799 adc controlled by an aduc847 microcontroller. Hx711 soic16 24 bit adc ic for load cell. The load cell can be directly interfaced to this adc.

Therefore this adc chip eliminates the need for external power regulator. So we can use hx711 ic which has all the above features simply removing complex circuitry. Consequently it will make your design cost effective. Working principle of the circuit is very simple.

With an onboard low noise amplifier onboard oscillator precision third order 24 bit delta sigma modulator and bridge power switch the ads1231 provides a complete front end solution for bridge sensor applications including weigh scales strain gauges and load cells. Load cell 40 kg. It interface with simple digital i o to any controller. All three features need three separate circuits and components adding to cost and complexity.

To measure weight using load cell we usually need regulated power source output amplifier noise reduced adc converter. Hx711 soic16 24 bit adc ic for load cell. How to use hx711. Also you can observe from the circuit diagram that we power the load cell from the hx711 chip.
