Introduction

AI Translation

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. The output stage’s unique design limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. The MAX985/MAX989/MAX993 have a push-pull output stage that sinks as well as sources current. Large internal output drivers allow rail-to-rail output swing with loads up to 8mA. The MAX986/MAX990/MAX994 have an open-drain output stage that can be pulled beyond VCC to 6V (max) above VEE. These open-drain versions are ideal for level translators and bipolar to singleended converters. The single MAX985 is available in a chip-scale package (UCSP), significantly reducing the required PC board area. The single MAX985/MAX986 are available in 5-pin SC70 packages and the dual MAX989/MAX990 are available in 8-pin SOT23 packages.
