Analog to Digital Converter (ADC)¶

The ADC samples the input signal at constant time intervals T (sample period) and converts it into a digital signal. The digital output signal is supplied to a single digital signal line. The ADC incorporates a sampler a converter and a quantizer that rounds the signal to positive integer values.

The sample period, the resolution of the quantizer and the upper and lower limit can be specified. The default value for the lower limit is zero.

When the input signal leaves the valid range, the Overflow or the Underflow output is set to logic high.

Example: Characteristic of an ADC with 3 bit resolution in the range of 0 to 10.

Note: The upper limit Rh corresponds to the binary value 1000 = 111 + 1.
