R2R DAC

A R-2R DAC (Resistor-2 Resistor Digital-to-Analog Converter) is a device that converts digital signals (like binary numbers from a computer) into continuous analog signals (like sound or images). It uses a network of resistors arranged in a specific pattern—mainly just two resistor values, R and 2R—to accurately translate bits into voltage levels. This design provides high precision, good stability, and is cost-effective, making it popular in audio and signal processing applications. Essentially, it transforms digital instructions into smooth, continuous signals that can drive speakers, displays, or other analog devices.
