MAX100数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

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.

简介

MAX100属于集成电路（IC）的模数转换器（ADC）。由制造生产的MAX100模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。
