MAX985/MAX986/MAX989/ MAX990/MAX993/MAX994 Micropower, Low-Voltage, UCSP/SC70, Rail-to-Rail I/O Comparators General Description The MAX985/MAX986/MAX989/MAX990/MAX993/ MAX994 single/dual/quad micropower comparators feature low-voltage operation and rail-to-rail inputs and outputs. Their operating voltages range from 2.5V to 5.5V, making them ideal for both 3V and 5V systems. These comparators also operate with ±1.25V to ±2.75V dual supplies. They consume only 11µA of supply current while achieving a 300ns propagation delay. Input bias current is typically 1.0pA, and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals.
