The minimum Conversion Time of MAX1204 is 5.5us, so how many samples will i get for 2Khz Sine wave ??
Oh, come on! Do you have a calculator? What is the period of one cycle of a 2 kHz sine wave? (Hint: the period, in seconds, is 1 / freqency, in Hz.) How many 5.5 µs periods will fit into the cycle period? (Another hint: use the division button on your calculator.)
See if you can work it out for yourself. If you want, you can post your answer here for us to check.
