whereNis the ADC's resolution in bits. If you were to connect the codes by lines (usually at code-transition boundaries), the ideal transfer function would plot a straight line. A line drawn through
int val = analogRead(A7); // read the ADC value from pin A7 Voltage = (ADC Value / ADC Resolution) * Reference Voltage float voltage = (float(val)/1024) * 3.6; //formulae to convert the ADC value to voltage lcd.setCursor(0, 0); // set the cursor to column 0, line 0 lcd.pr...
To achieve better performance, the SNR value should be higher.The above mentioned formula is a general definition for SNR. The SNR value of an ideal ADC is given by:SNR (dB) = 6.02N+1.76(dB)where N is the resolution (no. of bits) of the ADC.For 54、 example an ideal 10-bit ADC...
One of the performance spaces that SAR ADCs excel at is high resolution at relatively low speed. They find many applications ranging from medical imaging, instrumentation, to industrial process control, etc. Compared to sigma-delta ADCs, which are also well suited in the low speed space, SAR...
As an example, RES values for STM32L5 series can be 6.5, 8.5, 10.5 and 12.5 ADC clock cycles for 6, 8, 10 and 12-bit resolution. The ADC sampling rate or sample conversion time (TCONV) can be calculated using the following formula: TCONV = TSMPL + TSAR = 2.5 × TADC_...

More important, in a frequency analysis, you can see how the modulator shapes the noise to higher frequencies, facilitating the production of a higher resolution result. The modulator output in Figure 2 shows that the quantization noise of the modulator starts low at 0 Hz, rises rapidly, and ...

There is no need to incorporate a power-up delay or dummy conversions as the ADC128S102 is able to acquire the input signal to full resolution in the first conversion immediately following power-up. The first conversion result after power-up will be that of IN0. Bit 7 (MSB) DONTC Bit ...
