Solved: I am trying to find out the conversion time for ADC conversion time for S32k146. The formula of total conversion time is given in datasheet.
Solved: Hello Community, I am using S32K144 EVB , how to calculate the conversion and sampling time. My ADC operating frequency is 40MHZ. BR, Sarwath
In this type of analog-to-digital converter, the conversion time is independent of the input signal. The processing of one bit requires one clock cycle. For an n-bit converter, n-clock cycles are required. So, there is a general formula for conversion time. TC= n*Tclock Where, TC ...
When a conversion is initiated, the start of conversion signal is synchronized to the ADCCLK. This synchro- nization (TSYNC) can take from 0.5 to 1.5 ADCCLKs to occur. The total ADC conversion time TADC is calculated using the following formula: TADC = TSYNC + TACQ + TCONV Assuming ...
1.4 Conversion Mode A conversion mode determines how the ADC processes the input and performs the conversion operation. A standard ADC has basically two types of conversion modes. 1. Single ended conversion mode. 2. Differential conversion mode. ...
Setting a value in ADACQ register (ADACQH:ADACQH), then hardware will count out that number of ADC clock intervals, for acquisition time, before starting a conversion. Acquisition time calculation example in manual, is calculation of shortest time that may be used, ...
// See Datasheet for typical settle // time. ADC12CTL0 |= ADC12ENC; while(1) { ADC12CTL0 &= ~ADC12SC; ADC12CTL0 |= ADC12SC; // Sampling and conversion start __bis_SR_register(LPM4_bits + GIE); // LPM4 with interrupts enabled...
There is also this formula from the user guide section 34.2.6 for calculating the minimum sampling time. Here is the Ri and Ci from the datasheet. The first thing to note is your input resistance should be as low as possible....
