For example, the PIC18F452 microcontroller has 10-bit, 8-channel A/D converters. Most PIC microcontrollers with A/D features have multiplexed A/D converters where more than one analog input channel is provided. A/D converters are usually 8–10 bits having 256–1024 quantization levels. It is also possible to connect an external A/D converter to any type of microcontroller. Some microcontrollers have built-in A/D converters. ADC converters usually generate interrupts when a conversion is complete so that the user program can read the converted data quickly and efficiently.ĪDC converters are very useful in control and monitoring applications since most sensors (e.g., temperature sensor, pressure sensor, force sensor) produce analogue output voltages.ĭogan Ibrahim, in SD Card Projects Using the PIC Microcontroller, 2010 1.3.9 A/D ConverterĪn A/D converter is used to convert an analog signal like voltage to digital form so that it can be read and processed by a microcontroller. The ADC conversion process must be started by the user program, and it may take several tens of microseconds for a conversion to complete. For example, PIC32MX460F512L microcontroller has 16 channels of ADC converters, each 10-bit wide. Most PIC microcontrollers with ADC features have multiplexed ADC converters where more than one analogue input channel is provided. PIC32 microcontroller ADC converters are usually 10-bit wide, having 1024 quantisation levels. It is also possible to connect an external ADC converter to any type of microcontroller. Some microcontrollers have built-in ADC converters. 8 channel digital to analog converter Cirrus Logic CS4382 as used in a soundcard.Dogan Ibrahim, in PIC32 Microcontrollers and the Digilent chipKIT, 2015 1.3.8 Analogue-to-Digital ConverterĪn ADC is used to convert an analogue signal such as voltage to a digital form so that it can be read and processed by a microcontroller.
