Frequently Asked Questions
How can I increase the effective sampling rate using multiple MAX101 units?
Phase adjustment is available to optimize conversion for interleaving several MAX101s and achieving a higher effective sampling rate.
What kind of signal input range does this ADC support?
The analog input design accommodates either differential or single-ended use, offering a maximum range of ±270mV.
Is full-scale calibration of the input possible?
Yes, the dedicated reference input allows for full-scale calibration of the input range or can facilitate ratiometric measurements.
What structural element must be considered for high-speed operation?
The module requires proper thermal management; when operating at certain conditions, a heatsink may be necessary to maintain stable junction temperatures.
