  • 王小桃带你读文献:电流舵型DAC The Current-Steering DAC
    电流舵型DAC,其功能是将N-bits的数字信号Din转换为对应大小的模拟电流量Iout。 最简单的结构如下图所示,数字信号的每一位都通过开关来控制电流的输出,根据数字信号(二进制数)的位数,电流源的大小以2(二进制数的权重)的倍数增加,这样便实现了将数字信号转换为模拟的电流输出。 其中,D0代表最低有效位 (LSB,least significant bit),DN代表最高有效位 (MSB,most significant bit)。

  • IDAC(电流型DAC)的参数和性能测试-CSDN博客
    DAC一般是指输出电压型DAC,IDAC顾名思义输出是电流型DAC。 DAC是模数转换器 (ADC) 的功能补充,但两者面临的挑战却截然不同。 ADC的主要作用是在存在外部和内部噪声的情况下,将未知的随机输入信号连续数字化,并将结果传输到兼容的处理器。 不同于ADC,DAC的输入是来自处理器的稳定且有界的数字信号,不存在信噪比 (SNR) 问题。 然而,DAC输出却面临驱动外部负载的挑战,就电气上而言,这或许更为困难。 某些传感器和控制回路需要接入DAC来精确控制电流。
