Load Cell Adc Ic

How to use hx711.

Load cell adc ic.

The ads1231 is a precision 24 bit analog to digital converter adc. So we can use hx711 ic which has all the above features simply removing complex circuitry. It interface with simple digital i o to any controller. Working principle of the circuit is very simple.

Hx711 soic16 24 bit adc ic for load cell. Therefore this adc chip eliminates the need for external power regulator. 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. It consists of an ad7799 adc controlled by an aduc847 microcontroller.

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. Hx711 soic16 24 bit adc ic for load cell. All three features need three separate circuits and components adding to cost and complexity.

Also you can observe from the circuit diagram that we power the load cell from the hx711 chip. The load cell can be directly interfaced to this adc. To measure weight using load cell we usually need regulated power source output amplifier noise reduced adc converter. Consequently it will make your design cost effective.
