A sample and hold amplifier is connected to an ADC. The acquisition time of the sample and hold amplifier is 10 µsec and the conversion time of the ADC is 15 µsec. What is the highest possible data rate?
- A. 100 k samples
- B. 400 k samples
- C. 40 k samples
- D. 66 k samples
Answer: C. 40 k samples
Explanation: Total time $= (10+15)\mu sec=25~\mu sec$
Data rate $= \frac{1}{total~time} = \frac{1}{25\times10^{-6}} = 40~k~samples$.
