ADVANCE INFORMATION All information in this data sheet is preliminary MAXKLM and subject to change. rs . ; uae 1Gsps, 8-Bit ADC with Track/Hold General Description The MAX104 ECL-compatible, 1Gsps, 8-bit analog-to- digital converter (ADC) allows accurate digitizing of analog signals from DC to 1.5GHz. Designed with Maxim's proprietary advanced GST-2 bipolar process, the MAX104 contains a high-performance track/hold (T/H) amplifier and a quantizer on a single monolithic die. The innovative design of the internal T/H, which has an exceptionally wide input bandwidth of 1.5GHz, results in high, 7.3 effective bits performance at Nyquist. Special comparator design and decoding circuitry reduce out-of-sequence code errors and provide excel- lent metastable performance of less than one efror per 10'2 clock cycles. Unlike other ADCs, which can have errors that result in false full-scale or zero-scale out- puts, the MAX104 keeps the error magnitude to 1LSB. The analog input is designed for differential or single- ended use with a 300mV input range. Dual differential ECL-compatible output data paths provide for easy interfacing and include an 8:16 demultiplexer that reducs output data rates to one-half the clock rate. Control inputs are provided for interleaving additional MAX104 devices to increase the effective system sam- pling rate.
