Features:
711 is a 24-bit A/D converter chip specially designed for high-precision electronic scales. The required peripheral circuit has the advantages of high integration, fast response, strong anti-interference, etc., which reduces the cost of the whole electronic scale and improves the performance and reliability of the whole machine. The interface and programming of the chip and the back-end MCU chip are very simple, all control signals are driven by pins, and there is no need to program the internal registers of the chip. The input selection switch can arbitrarily select channel A or channel B, and its internal low-noise programmable amplifier connected, the programmable gain of channel A is 128 or 64, the corresponding full-scale differential input signal amplitude is ±20mV or ±40mV, channel B is a fixed gain of 32, which is used for system parameter detection. The voltage power supply can directly provide power to the external sensors and the A/D converter in the chip. No additional analog power supply is required on the system board. The clock oscillator in the chip does not require any external devices. The power-on automatic reset function simplifies the initialization of the boot. process.
