ADC clock is 10 MHz. ADC sampling time is 12.5 ADC clock cycles. Resolution is 12-bits. Determine conversion time.
First, we need to calculate the ADC cycle time:
ADC cycle time = 1 / ADC clock frequency
ADC cycle time = 1 / 10 MHz
ADC cycle time = 0.1 μs
Next, we calculate the conversion time:
Conversion time = Sampling time + (Resolution * ADC cycle time)
Conversion time = 12.5 * 0.1 μs + (12 * 0.1 μs)
Conversion time = 1.25 μs + 1.2 μs
Conversion time = 2.45 μs
Therefore, the conversion time for the ADC is 2.45 microseconds.
