WitrynaTconv = Sampling time + 12.5 cycles. Example: With an ADCCLK = 14 MHz and a sampling time of 1.5 cycles: Tconv = 1.5 + 12.5 = 14 cycles = 1 µs. The ADC Sampling Rate (Frequency) is calculated using this formula: SamplingRate = 1 / Tconv. For The Previous example where Tconv = 1µs, The samplingRate = 1000000 = 1Ms/sec.
