Special-purpose Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs) are electronic components designed to convert analog signals to digital form, or digital signals to analog form, with enhanced features or performance tailored for specific applications. Unlike general-purpose ADCs and DACs, special-purpose devices are optimized for parameters such as resolution, speed, linearity, noise immunity, input/output range, or multi-channel synchronization to meet the demands of complex and high-precision systems.
