MAX9030AXT-T/MAXIM，

Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators.

低成本、超薄、单/双/四单电源比较器

General DescriptionThe MAX9030/MAX9031/MAX9032/MAX9034 single/dual/quad comparators are optimized for single-supplyapplications from +2.5V to +5.5V but can also be oper-ated from dual supplies. These comparators have a188ns propagation delay and consume 35µA of supplycurrent per comparator over the -40°C to +125°C oper-ating temperature range. The combination of low-power, single-supply operation down to +2.5V, andultra-small footprint makes these devices ideal forportable applications.The MAX9030 is a low-cost single comparator withshutdown. The MAX9031, MAX9032, and MAX9034 arelow-cost single, dual, and quad comparators withoutshutdown, respectively. The comparators’ 4mV of built-in hysteresis provides noise immunity and preventsoscillations even with a slow-moving input signal. Theinput common-mode range extends from the negativesupply to within 1.1V of the positive supply. The designof the comparator output stage substantially reducesswitching current during output transitions, virtuallyeliminating power-supply glitches.The MAX9030 single comparator with shutdown is avail-able in the space-saving 6-pin SC70 and SOT23 pack-ages. The MAX9031 single comparator is available in tiny5-pin SC70 and SOT23 packages. The MAX9032 dualcomparator is available in 8-pin SOT23 and µMAX pack-ages, and the MAX9034 quad comparator is available ina 14-pin TSSOP package.

一般DescriptionThe MAX9030 / MAX9031 / MAX9032 / MAX9034单/双/四比较器优化single-supplyapplications + 2.5 v至+ 5.5 v,但也可以从双oper-ated供应。这些比较器a188ns传播延迟和消费35µa supplycurrent每比较器在-40°C + 125°C操作温度范围。低功耗,单电源操作+ 2.5 v,andultra-small足迹让这些设备理想的便携式应用程序播放器。一种低成本的单个comparator withshutdown MAX9030。MAX9031,MAX9032,MAX9034 arelow-cost单,双,分别和四排序withoutshutdown。比较器的4 mv的内置磁滞为噪声免疫力和preventsoscillations甚至提供了一个缓慢移动的输入信号。Theinput共模的范围内从negativesupply延伸到1.1 v的积极供给。将用比较器输出级大幅reducesswitching当前输出转换期间,virtuallyeliminating供电故障。MAX9030单一比较器的关闭是可用的节省空间的六脚SC70和SOT23 pack-ages。MAX9031单一比较器可以在tiny5-pin SC70和SOT23包。的MAX9032 dualcomparator可以在有SOT23和µMAX pack-ages,和MAX9034四比较器可以在14-pin TSSOP包。
