描述 Description

The MAX100 ECL-compatible, 250Msps, 8-bit analog-to-digital converter (ADC) allows accurate digitizing of analog signals from DC to 125MHz (Nyquist frequency). 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 single-ended 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 interfacing. These modes can be configured as either one or two identical latched ECL outputs. An 8:16 demultiplexer mode that reduces the output data rates to one-half the clock rate is also available.
For applications that require faster data rates, refer to Maxim's MAX101, which allows conversion rates up to 500Msps.

MAX100屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由制造生產(chǎn)的MAX100模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號(hào)。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。
