The central processing unit within a Digital-to-Analog Converter (DAC) responsible for transforming digital input signals into analog output signals.

技术定义

The Conversion Core is the fundamental component of a Digital-to-Analog Converter that executes the primary conversion algorithm. It interprets discrete digital codes (typically binary) and generates a corresponding continuous analog voltage or current waveform. Its performance directly determines the DAC's key specifications such as resolution, accuracy, linearity, and conversion speed.

工作原理

The core operates by receiving a digital input word (e.g., from a register or digital interface). Based on this input, it controls internal circuitry—such as a resistor ladder network (R-2R), current steering array, or sigma-delta modulator—to produce a precise analog output level proportional to the digital value. This process involves precise timing, reference voltage/current management, and often includes error correction mechanisms.
