MAX934:超低功耗、低成本比较器、内置2%电压基准

The MAX931–MAX934 single, dual, and quad micropower, low-voltage comparators plus an on-board 2% accurate reference feature the lowest power consumption available. These comparators draw less than 4µA supply current over temperature (MAX931), and include an internal 1.182V ±2% voltage reference, programmable hysteresis, and TTL/CMOS outputs that sink and source current. Ideal for 3V or 5V single-supply applications, the MAX931–MAX934 operate from a single +2.5V to +11V supply (or a ±1.25V to ±5V dual supply), and each comparator's input voltage range extends from the negative supply rail to within 1.3V of the positive supply. The MAX931–MAX934's unique output stage continuously sources as much as 40mA. And by eliminating power-supply glitches that commonly occur when comparators change logic states, the MAX931–MAX934 minimize parasitic feedback, making them easier to use. The single MAX931 and dual MAX932/MAX933 provide a unique and simple method for adding hysteresis without feedback and complicated equations, using the HYST pin and two resistors. For applications that require increased precision with similar power requirements, see the MAX921–MAX924 data sheet. These devices include a 1% precision reference.
