Load Cell Adc Ic

Also you can observe from the circuit diagram that we power the load cell from the hx711 chip.

Load cell adc ic.

The ads1231 is a precision 24 bit analog to digital converter adc. 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. Load cell 40 kg.

Hx711 soic16 24 bit adc ic for load cell. 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. The load cell can be directly interfaced to this adc. Figure 5 is a block diagram of a reference design a weigh scale system evaluation board designed at analog devices.

When we apply weigh on the load cell it produces an. All three features need three separate circuits and components adding to cost and complexity. Therefore this adc chip eliminates the need for external power regulator. It interface with simple digital i o to any controller.

Working principle of the circuit is very simple. Consequently it will make your design cost effective. 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.
