Designed with Maxim’s proprietary advanced bipolar processes, the MAX100 contains a high-performance track/hold (T/H) amplifier and a quantizer in a single ceramic strip-line package.
The innovative design of the internal T/H assures an exceptionally wide input bandwidth of 1.
2GHz and aperture delay uncertainty of less than 2ps, resulting in a high 6.
8 effective bits performance.
Special comparator output design and decoding circuitry reduce out-of-sequence code errors.
The probability of erroneous codes occurring due to metastable states is reduced to less than 1 error per 1015 clock cycles.
Unlike other ADCs, which can have errors that result in false full-scale or zero-scale outputs, the MAX100 keeps the magnitude to less than 1LSB.
The analog input is designed for either differential or singleended use with a ±270mV range.
Sense pins for the reference input allow full-scale calibration of the input range or facilitate ratiometric use.
Midpoint tap for the reference string is available for applications that need to modify the output coding for a user-defined bilinear response.
Use of separate high-current and low-current ground pins provides better noise immunity and highest device accuracy.
Dual output data paths provide several data output modes for easy int...
