MAX985, MAX986, MAX989, MAX990, MAX993, MAX994 Micropower, Low-Voltage, UCSP/SC70, Rail-to-Rail I/O Comparators

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 11A 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 s 68c ources 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 single-ended 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.
