Features:
It has the advantages of high integration, fast response speed, and strong anti-interference. It reduces the overall cost of the electronic scale and improves the performance and reliability of the whole machine.
The interface and programming are very simple. All control signals are driven by pins, and there is no need to program the registers inside the chip.
The input selection switch can select channel A or channel B at will, and connect it to its internal low-noise programmable amplifier. The programmable gain of channel A is 128 or 64, and the corresponding full-scale differential input signal amplitude is ±20mV or 40mV respectively. Channel B is a fixed gain of 32, which is used for system parameter detection.
The regulated power supply provided in the chip can directly provide power to external sensors and the A/D converter in the chip, and no additional analog power supply is required on the system board.
