_______________General Description

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.

The common-mode input voltage range extends 250mV
beyond the supply rails. 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.

The output stage’s unique design limits supply-current
surges while switching, virtually eliminating the supply
glitches typical of many other comparators. This design
also minimizes overall power consumption under
dynamic conditions. The MAX987/MAX991/MAX995
have a push/pull output stage that sinks as well as
sources current. Large internal output drivers allow rail­to-rail output swing with loads up to 8mA. The
MAX988/MAX992/MAX996 have an open-drain output
stage that can be pulled beyond VCCto 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
SOT23 packages.

FUNCTION

_______________Detailed Description

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-to­rail 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 open­drain output stage that can be pulled beyond VCCto 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
supply-current change during an output transition is
extremely small. The

Typical Operating Characteristics

graph Supply Current vs. Output Transition Frequency
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, battery-powered applications.

__________Applications Information

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 (V

REF

-

V

OUT

) / R3. Considering the two possible output
states and solving for R3 yields two formulas: R3 =
V

REF

/ 1µA or R3 = (V

REF

- VCC) / 1µA. Use the
smaller of the two resulting resistor values. For
example, if V

REF

= 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 VINrising (V

THR

; V

THF

is
the trip point for VINfalling). This is the threshold
voltage at which the comparator switches its output
from low to high as VINrises above the trip point. For
this example, choose 3V.

5) Calculate R2 as shown. For this example, choose an

8.2kΩ standard value:

6) Verify trip voltages and hysteresis as follows:

MAX988/MAX992/MAX996

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

Use the following procedure to calculate resistor
values:

1) Select R3 according to the formulas R3 = V

REF

/ 1µA

or R3 = (V

REF

- VCC) / 1µA - R4. Use the smaller of

the two resulting resistor values.

2) Choose the hysteresis band required (VHB). For this
example, choose 50mV.

3) Calculate R1 according to the following equation:

R1 = (R3 + R4) x (VHB/ VCC)

4) Choose the trip point for VINrising (V

THR

; V

THF

is
the trip point for VINfalling). This is the threshold
voltage at which the comparator switches its output
from low to high as VINrises above the trip point.

5) Calculate R2 as follows:

6) Verify trip voltages and hysteresis as follows:

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 printed circuit board with an unbroken, low­inductance ground plane.

2) Place a decoupling capacitor (a 0.1µF ceramic
capacitor is a good choice) as close to VCCas
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 printed circuit
board 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 lev­els to 3V logic levels. The MAX988 is powered by the +5V
supply voltage, and the pull-up 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 VCCand the +5V supply to the pull-up resistor.
