MAX987/MAX988/MAX991/
MAX992/MAX995/MAX996
High-Speed, Micropower, Low-Voltage,
Rail-to-Rail I/O Comparators
General Description
Benefits and Features
● 120ns Propagation Delay
The
MAX987/MAX988/MAX991/MAX992/MAX995/
MAX996 single/dual/quad micropower comparators
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 systems.
These comparators also operate with ±1.25V to ±2.75V
dual supplies. They consume only 48μA per comparator
while achieving a 120ns propagation delay.
● 48μA Quiescent Supply Current
● +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
8mA Current (MAX987/MAX991/MAX995)
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.
● Open-Drain Output Voltage Extends Beyond V
CC
(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. The MAX987/
MAX991/MAX995 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 MAX988/MAX992/MAX996 have an open-drain
Current, Minimizing Overall Power Consumption
● 100μA Supply Current at 1MHz Switching
Frequency
● No Phase Reversal for Overdriven Inputs
● Available in Space-Saving Packages:
• 5-Pin SC70 (MAX987/MAX988)
• 8-Pin μMAX (MAX991/MAX992)
