一、概述 CH7106是双积分式的3(1/2)位数A/D转换器.具有单片集成、高输入阻抗、宽电源电压、宽工作温度范围、低噪声、低失调、低温漂以及可以浮地工作等许多特点,因此在仪器仪表及其他许多领域中,广泛用来将模拟量转换为数字量。 CH7106可直接驱动液晶显示器,无须另加显示器驱动器件,使用非常方便。但其内部对输入模拟信号工作在连续采样状态,而输出的数字段码信号数量多而且没有锁存功能,所以当把用CH7106装配的仪
I. Overview CH7106 is a dual integral 3 (1/2) digit A / D converter with monolithic integration, high input impedance, wide supply voltage, wide operating temperature range, low noise, low offset, low temperature drift and Can float to work and many other features, so in instrumentation and many other areas, widely used to convert analog to digital. CH7106 can directly drive the LCD display, without additional display driver devices, the use of very convenient. However, the internal analog input signal to work in continuous sampling state, and the number of output digital signal segment code and there is no latching function, so when using CH7106 assembly of the instrument
