Input range adc

The input signal is usually an analog voltage, and the output is a binary number. The ADC precision is the number of distinguishable ADC inputs (e.g., 4096 alternatives, 12 bits). The ADC range is the maximum and minimum ADC input (e.g., 0 to +3.3V).

What are ADC inputs?

ADC = Analog to Digital Converter. An analog input converts a voltage level into a digital value that can be stored and processed in a computer.

How do I increase my ADC range?

Placing a resistor in series with the ADC input will increase the voltage range for the ADC.

What is full scale range in ADC?

Full Scale Range (FSR) Full Scale Range is the range defined by the reference inputs of the ADC If the ADC has only a positive reference input and the negative reference input is tied to ground FSR = VRef+, otherwise FSR = VRef+ - VRef-.

What is the input range of the analog input?

Analog value: from 0 to 4095 (12 bit). If the analog input is: below 0V/0mA, then the analog value will be 0. above 10V/20mA (about 2% above the full scale), then the analog value will be 4096.
