The conversion time is &lt;2 µs, and the smallest configurable acquisition time is 3 µs. This will give a total sample time of 5 µs, and give your the maximum sample rate of 200 ksps (1/5µs = 200 kHz). If you need higher acquisition time, the maximum sample rate will decrease.</li> </ol> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
