What does Analog Devices do? Answer: Analog Devices (ADI) designs analog, mixed-signal, and digital signal processing (DSP) ICs. Their chips convert real-world signals (sound, temperature, pressure) into digital data and vice-versa. Example: Sensor → Analog signal ADI ADC → Digital signal → Processor 2️⃣ What is analog signal vs digital signal? Answer: Analog signal: Continuous values (e.g., microphone sound) Digital signal: Discrete values (0s and 1s) ADI mainly works on high-precision analog + digital conversion.
