    • Analog-to-digital converting circuitry includes first and second analog-to-digital converting units. A converting start controlling circuit sends out converting start timing signals START1 and START2 which are out of phase with each other. When the first or second analog-to-digital converting unit receives the corresponding converting start timing signal START1 or START2 from the converting start controlling circuit, it samples and holds an analog value of an input signal, and then successively converts the analog value into an n-bit digital signal bit-by-bit and sends out the digital signal. An output selecting circuit outputs the digital signals from the first and second analog-to-digital converting units alternatingly.
    • 模数转换电路包括第一和第二模数转换单元。 A转换开始控制电路发送彼此异相的转换开始定时信号START1和START2。 当第一或第二模数转换单元从转换开始控制电路接收到相应的转换开始定时信号START1或START2时,其采样并保持输入信号的模拟值,然后连续地将模拟值转换为 n位数字信号逐位发送出数字信号。 输出选择电路交替地输出来自第一和第二模数转换单元的数字信号。
