The innovative design of the internal T/H, which has an exceptionally wide 2.2GHz full-power input bandwidth, results in high performance (greater than 7.5 effective bits) at the Nyquist frequency. A fully differential comparator design and decoding circuitry reduce out-ofsequence code errors (thermometer bubbles or sparkle codes) and provide excellent metastable performance of one error per 1016 clock cycles. Unlike other ADCs that can have errors resulting in false full- or zero-scale outputs, the MAX104 limits the error magnitude to 1LSB.
