MAX968EUA

单/双/四路，微功耗，超低电压，轨至轨I / O比较 Single/Dual/Quad, Micropower, Ultra-Low-Voltage, Rail-to-Rail I/O Comparators

General Description

The MAX965–MAX970 single/dual/quad micropower comparators feature Rail-to-Rail®inputs and outputs, and

fully specified single-supply operation down to +1.6V. These devices draw less than 5µA per comparator and have open-drain outputs that can be pulled beyond VCC to 6V max above ground. In addition, their rail-to-rail input common-mode voltage range makes these comparators suitable for ultra-low-voltage operation.
