♦ 120ns Propagation Delay

The MAX987/MAX988/MAX991/MAX992/MAX995/

MAX996 single/dual/quad micropower comparators

♦ 48µA Quiescent Supply Current

feature low-voltage operation and Rail-to-Rail inputs

and outputs. Their operating voltage ranges from +2.5V

to +5.5V, making them ideal for both 3V and 5V sys-

tems. These comparators also operate with ±1.25V to

±2.75V dual supplies. They consume only 48µA per

comparator while achieving a 120ns propagation delay.

♦ +2.5V to +5.5V Single-Supply Operation

♦ Common-Mode Input Voltage Range Extends

250mV Beyond the Rails

♦ Push/Pull Output Stage Sinks and Sources

The common-mode input voltage range extends 250mV

beyond the supply rails. Input bias current is typically

1.0p A, a nd inp ut offs e t volta g e is typ ic a lly 0.5mV.

even with slow-moving input signals.

8mA Current (MAX987/MAX991/MAX995)

♦ Open-Drain Output Voltage Extends Beyond V

(MAX988/MAX992/MAX996)

♦ Unique Output Stage Reduces Output Switching

The output stage’s unique design limits supply-current

surges while switching, virtually eliminating the supply

glitches typical of many other comparators. This design

a ls o minimize s ove ra ll p owe r c ons ump tion und e r

dynamic conditions. The MAX987/MAX991/MAX995

have a push/pull output stage that sinks as well as

sources current. Large internal output drivers allow rail-

to-ra il outp ut s wing with loa d s up to 8mA. The

MAX988/MAX992/MAX996 have an open-drain output

Current, Minimizing Overall Power Consumption

♦ No Phase Reversal for Overdriven Inputs
