ADC (Analog-to-Digital Converter)
makerAnalog-to-Digital Converter, a system that converts analog signals to digital data.
expanded
An ADC is an electronic device used to transform analog voltage levels into discrete digital numbers, allowing microcontrollers and computers to process real-world analog inputs. ADCs are crucial in applications where digital systems are interfacing with analog signals, such as in data acquisition systems and audio recording.
examples
The MCP3008 is an 8-channel 10-bit ADC used in conjunction with the Raspberry Pi for reading analog sensors.
This ADC is commonly used in maker projects requiring multiple sensor inputs, such as environmental monitoring systems, where it translates analog readings from temperature or light sensors into digital data for processing by the Raspberry Pi.
The ADS1115 is a precision 16-bit ADC used in sensitive instrumentation projects.
Utilized in applications needing high precision and accuracy, such as scientific experiments or medical devices, the ADS1115 provides precise readings from sensors, with programmable gain to accommodate varying signal ranges.
