Often, the required output signal is another analog output signal, which requires a digital to analog converter.

通常，要求的输出信号为另一个模拟输出信号，这就需要数模转换器。

As a special interface connected with analog and digital circuits, high performance analog-to-digital converter is much more important in whole system design.

作为模拟电路与数字电路的接口电路，高性能的模数转换器对整个设计系统的实现非常重要。

Only a few of these modular components have been designed so far: the AVR-X (an Arduino-compatible microcontroller), FRAM-X (512 byte chunks of stackable Ferroelectric RAM) and ADC-X (an 8-channel analog to digital converter).

Those charges are funneled en masse through a single analog-to-digital converter, which outputs each pixel's value in ones and zeros.

Pixim's innovation is to give each pixel its own analog-to-digital converter so that photons are continuously converted to ones and zeros and the camera's microprocessor can tell exactly how fast each pixel is filling up relative to the other pixels.
