Description:
CJMCU-711 is designed for high-precision electronic scales designed for 24-bit A / D converter chips. Compared with the same type of other chip that integrates the peripheral circuits including power supply, on-chip clock oscillator and others required the same type of chip, high integration, fast response, and strong anti-interference advantages. Reducing the overall cost of the electronic scales and improving the overall performance and reliability. The chip with the rear end of the MCU chip interface and programming is very simple, all control signals from the pin driver, do not need to register the chip programming. Input selector switch can be arbitrarily selected channel A or channel B, its internal programmable low noise amplifier is connected. Channel A programmable gain of 128 or 64, corresponding to the full amount of the differential input signal amplitude was ± 20mV or ± 40mV. Channel B, compared with a fixed gain of 32 for the system parameter detection. The chip can provide the power supply to provide power directly to the A external sensor and chip A / D converter, analogue system board without additional power supply. Chip clock oscillator does not require any external components. Automatic power-on reset function to simplify the initialization process boot.
