ADC Resolution - Coggle Diagram
ADC Resolution
Factors Affecting Resolution
Reference Voltage Stability
Noise and fluctuation
ADC Bit Depth
8-bit, 10-bit, 12-bit
Sampling Rate
Nyquist criterion
Importance in Microcontrollers
Affects measurement accuracy
Higher resolution → finer detail
Used in sensor data acquisition
Temperature, light, pressure sensors
Definition
Converts Analog → Digital
Each bit = quantization step
Voltage signal into binary
Formula
Resolution = Vref / (2ⁿ - 1)
Vref: Reference Voltage
n: Number of bits
Example Calculation
Vref = 5V, n = 10 bits
Step = 5 / (2¹⁰ - 1) = 4.88 mV per step
