Calculating thee resolution of an analog- to-digital converter (ADC) in sensors is essential for commercing thoe precision of measurements. It determinates how finely the sensor can diferenish between different input voltage levels. This article explicains thee basic methodo calculate ADC resolution.
Understanding ADC Resolution
Te resolution of an ADC is the small ett change in voltage that be detected by thy converter. It is typically expressed in bits, such as 8-bit, 10-bit, or 12-bit resolution. Higher bits mean hier resolution and more precise measurements.
Methodol kalkulationu
Te resolution can bee calculated using thee following formula:
CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; - 1) CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3c;
Where:
- CLANE1; CLANE1; FLT: 0 CLANE3; CLANE3; Reference Voltage CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; is them maximum voltage the ADC can measure.
- CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; is them number of bits of the ADC.
Example Calculation
If an ADC has a 5V reference voltage and a 10-bit resolution, thee calculation is:
CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; - 1) = 5V / 1023 CLANEx489V CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3;
This means the ADC can detect voltage changes as small as approatele 4.89 millivolts.
