ower supply, the conversion rate to a maximum 20 MPS, with a sampling of internal circuits and to maintain the benchmark resistance. The chip's biggest advantage is fast, simple control, programmable device to control. A / D circuit as follows:Р The A / D circuit of the dynamic range of input signal for a small 0.59 V ~ 2.59V. In order to be extended to the dynamic range of 0 ~ 10 V, to be in its previous level by adding the following adjustment circuit. In addition to the circuit five times the input signal attenuation, the input signal is still on the superposition of the 1.5 V DC.Р Control circuitry to do the programmable device, the main address cumulative unit, sampling speed option modules and programmable device and MCU interface unit. The address cumulative unit circuit as follows:
