Cirrus Logic Mixed-Signal Leadership

Mixed-Signal Technologies Explained

• Analog-to-Digital Converter (ADC)
• Used for Microphone or other analog

inputs in audio systems

ADC

• CODEC (ADC + DAC)
• Used in surround sound systems
• Mainly multi-channel DAC + single

ADC

• Digital to Analog Converter (DAC)
• Used for converting digital back to

analog so they can be sent to amp/ speaker

Interface

• Digital Interface (S/PDIF)
• Digital In/Out
• Connects digital devices like DVD

player and AVR
