About ADC (Analog to Digital Converters)

ADCs convert continuous analog signals into discrete digital values. The conversion process involves sampling, quantization, and encoding the analog input.

Key ADC Parameters:

  • Resolution: Number of bits determining precision
  • Sampling Rate: How often the ADC samples the input
  • Reference Voltage: Defines the input voltage range
  • SNR: Signal-to-noise ratio in decibels

ADC Types:

  • SAR (Successive Approximation): Fast, medium resolution
  • Delta-Sigma: High resolution, lower speed
  • Flash: Very fast, low resolution
  • Pipeline: High speed, high resolution

Applications:

  • Data acquisition systems
  • Digital audio recording
  • Sensor interfacing
  • Digital oscilloscopes
  • Medical instrumentation
