What does the term 'DAC' refer to in a microprocessor circuit?

Explanation:
In a microprocessor circuit, the term DAC refers to a Digital-to-Analog Converter. It takes a binary digital word from the processor and converts it into a corresponding analog voltage (or current). The exact output level is determined by the input code and the reference voltage, so more bits mean finer voltage steps. DACs are how digital systems produce real-world analog signals, such as audio levels, control voltages for devices, or smooth ramps for motors. Common implementations include resistor ladders like R-2R networks or conversion methods such as successive approximation, and they often interface with the CPU via parallel or serial connections. The other names listed don’t describe a standard component used to create analog signals from digital data.
