Voltage-based Digital to Analog Converters (DACs) can suffer from issues like non-linearity, limited output range, and susceptibility to noise, which can affect signal integrity. Common topologies for voltage-based DACs include resistor ladder networks and weighted resistor configurations. In contrast, current-based DACs often utilize current steering techniques and can provide better performance in terms of linearity and speed. Understanding these differences is crucial for selecting the appropriate DAC type for specific applications. Overall, the choice between voltage and current-based DACs depends on the requirements of the project.
