Mixed-signal IC: what it means.
A mixed-signal IC includes both analog and digital circuitry. This can connect physical-world measurements or outputs with digital processing inside one device. Infineon identifies mixed-signal integration as combining analog and digital circuit types. (Infineon: semiconductor glossary)
The presence of digital control does not remove the analog signal path. Evaluate both sides: the analog range and performance, and the digital interface and operating requirements. Integration is not a substitute for either set of specifications. (Infineon: semiconductor glossary)
Put the definition to work.
A sensor interface may need to handle a small analog signal and deliver digital data. Calling it mixed-signal helps describe that combination, rather than placing it in only one category.
Questions to ask next.
Use these questions as a reading checklist, not as a device-selection recommendation. Exact manufacturer documentation takes priority over a general definition.
- Analog ranges and signal path
- Digital interface and timing
- Power and layout guidance from the manufacturer

Common Mixed-signal IC questions.
Is an ADC a useful mixed-signal example?
Yes. Analog-to-digital conversion connects an analog input with a digital representation. The surrounding functions and exact implementation depend on the device. (Infineon: semiconductor glossary)
