High-Speed, Micropower, Low-Voltage,
Rail-to-Rail I/O Comparators
General Description
Benefits and 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 comparator
while achieving a 120ns propagation delay.
●● 120ns 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.
●● Open-Drain Output Voltage Extends Beyond VCC
(MAX988/MAX992/MAX996)
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
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 MAX987/MAX988 are available in tiny 5-pin
SC70 packages, while the dual MAX991/MAX992 are
available in ultra-small μMAX® package.

Rail-to-Rail I/O Comparators
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 propagation 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.
The output stage employs a unique design that minimizes
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-drain output
stage that can be pulled beyond VCC to an absolute maximum
of 6V above VEE.
Input Stage Circuitry
The devices’ input common-mode range extends from
-0.25V to (VCC + 0.25V). These comparators may operate 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 protected from
overvoltage by internal body diodes connected to the
supply rails. As the input voltage exceeds the supply rails,
these body diodes become forward biased and begin to
conduct. Consequently, bias currents increase exponentially
as the input voltage exceeds the supply rails.
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 operation.
However, with this family of comparators, the supplycurrent change during an output transition is extremely
small. The Supply Current vs. Output Transition Frequency
graph in the Typical Operating Characteristics section
shows the minimal supply-current increase as the output
switching frequency approaches 1MHz. This characteristic
eliminates the need for power-supply filter capacitors to
reduce glitches created by comparator switching currents.
Battery life increases substantially in high-speed, batterypowered applications.
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 calculate 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
current through R3 at the trip point is (VREF - VOUT)
/ R3. Considering the two possible output states and
solving for R3 yields two formulas: R3 = VREF / 1µA or
R3 = (VREF - VCC) / 1µA. Use the smaller of the two
resulting resistor values. For example, if VREF = 1.2V
and VCC = 5V, then the two R3 resistor values are
1.2MΩ and 3.8MΩ. Choose a 1.2MΩ standard value
for R3.
2) Choose the hysteresis band required (VHB). For this
example, choose 50mV.
3) Calculate R1 according to the following equation:
R1 = R3 x (VHB / VCC)
For this example, insert the values R1 = 1.2MΩ x
(50mV / 5V) = 12kΩ.
4) Choose the trip point for VIN rising (VTHR; VTHF is
the trip point for VIN falling). This is the threshold
voltage at which the comparator switches its output
from low to high as VIN rises above the trip point. For
this example, choose 3V.

Circuit Layout and Bypassing
These comparators’ high-gain bandwidth requires design
precautions to maximize their high-speed capability. The
recommended precautions are:
1) Use a PCB with an unbroken, low-inductance ground
plane.
2) Place a decoupling capacitor (a 0.1µF ceramic
capacitor is a good choice) as close to VCC as
possible.
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.

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.
Figure 4 shows an application that converts 5V logic levels
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 voltage.
This configuration allows the full 5V logic swing without
creating overvoltage on the 3V logic inputs. For 3V to 5V
logic-level translation, simply connect the +3V supply to
VCC and the +5V supply to the pullup resistor.
