Bipolar ADC Calculator

This tool calculates the full scale range and resolution of a Bipolar ADC

Enter:

  • Reference Voltage (VREF)
  • Number of Bits in the ADC (n)
  • Programmable Gain Linear Value (PGA)


	

			

		

						

				

				

                

			

			
						

		

		











Example Calculation





A 12-bit Bipolar ADC with a reference voltage value of 5 Volt has a resolution of 1.22 mV. 





Formula





Full Scale Range (FSR) = VREF/PGA





1 LSB = VREF/2n

Background





A Bipolar Analog-to-Digital Converter (ADC) is a type of ADC that is capable of converting both positive and negative voltage values into a digital representation. 





Unlike unipolar ADCs, which can only process positive voltages, bipolar ADCs can handle a range of voltages around zero. This capability makes bipolar ADCs particularly useful in applications where the input signal can swing above and below ground level, such as in audio processing, signal analysis, and various scientific and industrial applications.
