Detailed Description
The MAX9025/MAX9026 feature an on-board 1.236V
±1% reference, yet draw an ultra-low supply current of
1.0A. The MAX9027/MAX9028 (without reference)
consume just 0.6A of supply current. All four devices
are guaranteed to operate down to +1.8V. Their com-
mon-mode input voltage range extends 200mV
beyond-the-rails. Internal hysteresis ensures clean out-
put switching, even with slow-moving input signals.
Large internal output drivers allow rail-to-rail output
swing with up to ±5mA loads.
The output stage employs a unique design that mini-
mizes supply-current surges while switching, virtually
eliminating the supply glitches typical of many other
comparators. The MAX9025/MAX9027 have a push-pull
output stage that sinks as well as sources current. The
MAX9026/MAX9028 have an open-drain output stage
that can be pulled beyond VCC to a maximum of 5.5V
above VEE. These open-drain versions are ideal for
implementing wire-OR output logic functions.
Input Stage Circuitry
The input common-mode voltage range extends from
VEE - 0.2V to VCC + 0.2V. These comparators operate
at any differential input voltage within these limits. Input
bias current is typically ±0.15nA if the input voltage is
between the supply rails. Comparator inputs are pro-
tected from overvoltage by internal ESD protection
diodes connected to the supply rails. As the input volt-
age exceeds the supply rails, these ESD protection
diodes become forward biased and begin to conduct.
Output Stage Circuitry
The MAX9025–MAX9028 contain a unique break-
before-make output stage capable of rail-to-rail opera-
tion with up to ±5mA loads. Many comparators
consume orders of magnitude more current during
switching than during steady-state operation. However,
with this family of comparators, the supply-current
change during an output transition is extremely small.
In the Typical Operating Characteristics, the Supply
Current vs. Output Transition Frequency graphs show
the minimal supply-current increase as the output
switching frequency approaches 1kHz. This character-
istic reduces the need for power-supply filter capaci-
tors to reduce glitches created by comparator
switching currents. In battery-powered applications,
this characteristic results in a substantial increase in
battery life.
