________________General Description
____________________________Features
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 compara-
tor while achieving a 120ns propagation delay.
♦ 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
Input bias current is typically 1.0pA, and input offset volt-
age 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
MAX987/MAX991/MAX995 have a push-pull output
stage that sinks as well as sources current. Large inter-
nal output drivers allow rail-to-rail output swing with
loads up to 8mA. The MAX988/MAX992/MAX996 have
an open-drain output stage that can be pulled beyond

Detailed Description
Applications Information
The MAX987/MAX988/MAX991/MAX992/MAX995/
MAX996 are single/dual/quad low-power, low-voltage
comparators. They have an operating supply voltage
range between +2.5V and +5.5V and consume only
48µA per comparator, while achieving 120ns propaga-
tion delay. Their common-mode input voltage range
extends 0.25V beyond each rail. Internal hysteresis
ensures clean output switching, even with slow-moving
input signals. Large internal output drivers allow rail-to-
rail output swing with up to 8mA loads.
Additional Hysteresis
MAX987/MAX991/MAX995
The MAX987/MAX991/MAX995 have 2.5mV internal
hysteresis. Additional hysteresis can be generated with
three resistors using positive feedback (Figure 1).
Unfortunately, this method also slows hysteresis
response time. Use the following procedure to calcu-
late resistor values for the MAX987/MAX991/MAX995.
1) Select R3. Leakage current at IN is under 10nA;
therefore, the current through R3 should be at least
1µA to minimize errors caused by leakage current.
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 MAX987/MAX991/MAX995 have a
push-pull output structure that sinks as well as sources
current. The MAX988/MAX992/MAX996 have an open-
The current through R3 at the trip point is (V
-

) / R3. Considering the two possible output
OUT
states and solving for R3 yields two formulas: R3 =
V
/ 1µA or R3 = (V - V ) / 1µA. Use the

R3 resistor values are 1.2MΩ and 3.8MΩ. Choose a
1.2MΩ standard value for R3.

ate at any differential input voltage within these limits.
Input bias current is typically 1.0pA if the input voltage
is between the supply rails. Comparator inputs are pro-
tected from overvoltage by internal body diodes con-
nected to the supply rails. As the input voltage exceeds
the supply rails, these body diodes become forward
biased and begin to conduct. Consequently, bias cur-
rents increase exponentially as the input voltage
exceeds the supply rails.
3) Calculate R1 according to the following equation:
R1 = R3 x (V / V
)
CC

For this example, insert the values R1 = 1.2MΩ x
(50mV / 5V) = 12kΩ.
4) Choose the trip point for V rising (V

from low to high as V rises above the trip point. For

Output Stage Circuitry
These comparators contain a unique output stage
capable of rail-to-rail operation with up to 8mA loads.
Many comparators consume orders of magnitude more
current during switching than during steady-state oper-
ation. However, with this family of comparators, the
supply-current change during an output transition is
extremely small. The Typical Operating Characteristics
Supply Current vs. Output Transition Frequency graph
shows the minimal supply-current increase as the out-
put switching frequency approaches 1MHz. This char-
acteristic eliminates the need for power-supply filter
capacitors to reduce glitches created by comparator
switching currents. Battery life increases substantially
in high-speed, battery-powered applications.

MAX988/MAX992/MAX996
The MAX988/MAX992/MAX996 have 2.5mV internal
hysteresis. They have open-drain outputs and require
an external pullup resistor (Figure 2). Additional hys-
teresis can be generated using positive feedback, but
the formulas differ slightly from those of the
MAX987/MAX991/MAX995.

Circuit Layout and Bypassing
These comparators’ high-gain bandwidth requires
design precautions to maximize their high-speed capa-
bility. The recommended precautions are:

3) On the inputs and outputs, keep lead lengths short
to avoid unwanted parasitic feedback around the
comparators.

4) Solder the devices directly to the PCB instead of
using a socket.

Zero-Crossing Detector
Figure 3 shows a zero-crossing detector application.
The MAX987’s inverting input is connected to ground,
and its noninverting input is connected to a 100mVp-p
signal source. As the signal at the noninverting input
crosses 0V, the comparator’s output changes state.
Logic-Level Translator
Figure 4 shows an application that converts 5V logic lev-
els to 3V logic levels. The MAX988 is powered by the +5V
supply voltage, and the pullup resistor for the MAX988’s
open-drain output is connected to the +3V supply volt-
age. This configuration allows the full 5V logic swing with-
out creating overvoltage on the 3V logic inputs. For 3V to
5V logic-level translation, simply connect the +3V supply
to V and the +5V supply to the pullup resistor.
