Microchips (or integrated circuits, ICs) come in many forms, but they are generally categorized into three main types based on their function:
1. Analog Chips
These chips process continuous signals like sound, temperature, or voltage.
Function: Amplify, filter, or convert signals.
Examples:
Operational amplifiers (op-amps)
Voltage regulators
Analog-to-Digital Converters (ADC)
Sensor interface chips
2. Digital Chips
These handle discrete binary data (0s and 1s).
Function: Perform logic operations, processing, storage.
Examples:
Microprocessors (CPUs)
Microcontrollers (MCUs)
Memory chips (RAM, ROM, Flash)
Logic gates, flip-flops, counters
3. Mixed-Signal Chips
These combine analog and digital functions on a single chip.
Function: Allow interaction between the real world (analog) and digital systems.
Examples:
System-on-Chip (SoC)
Digital Signal Processors (DSPs)
Wireless transceivers (Bluetooth, Wi-Fi)
Touch controllers
