Single/Dual/Quad, SOT23, Single-Supply,
High-Speed, Low-Power Comparators
____________________________Features
The MAX976/MAX978/MAX998 dual/quad/single, highspeed, low-power comparators are optimized for
+3V/+5V single-supply applications. They achieve a
20ns propagation delay while consuming only 225µA
supply current per comparator. The MAX998 features a
low-power shutdown mode that places the output in a
high-impedance state and reduces supply current
to 1nA.
The MAX976/MAX978/MAX998 inputs have a commonmode voltage range that extends 200mV below ground.
Their outputs are capable of rail-to-rail operation without external pullup circuitry, making these devices ideal
for interface with CMOS/TTL logic. All inputs and outputs can tolerate a continuous short-circuit fault condition to either rail. The comparators’ internal hysteresis
ensures clean output switching, even with slow-moving
input signals.
For space-critical applications, the single MAX998 is
available in a 6-pin SOT23 package, the dual MAX976
is available in an 8-pin µMAX® package, and the quad
MAX978 is available in a 16-pin QSOP package.

Note 1: The MAX998EUT specifications are 100% tested at TA = +25°C. Limits over the extended temperature range are guaranteed by design, not production tested.
Note 2: Inferred from CMRR test. Either input can be driven to the absolute maximum limit without false output inversion, as long as
the other input is within the common-mode voltage range.
Note 3: VOS is defined as the mean of trip points. The trip points are the extremities of the differential input voltage required to make
the comparator output change state (Figure 1).
Note 4: The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis zone (Figure 1).
Note 5: Propagation Delay is guaranteed by design. For low overdrive conditions, VTRIP (Figure 1) is added to the overdrive.
Note 6: Propagation-Delay Skew is the difference between the positive-going and the negative-going propagation delay.
Note 7: For design purposes, the tEN can be as high as 60µs.

__________________Detailed Description
The MAX976/MAX978/MAX998 dual/quad/single comparators operate from a single +2.7V to +5.5V supply.
They achieve a 20ns propagation delay while consuming only 225µA of supply current per comparator. The
MAX998 features a low-power shutdown mode that
places the output in a high-impedance state and
reduces supply current to 1nA. Activate shutdown
mode by driving SHDN low.
The MAX976/MAX978/MAX998 comparator inputs have
a common-mode voltage range of -0.2V to (VCC - 1.2V).
Shutdown Input. Drive low for shutdown mode. Drive high or connect to VCC for normal operation.
Either input can be driven to the Absolute Maximum
Ratings limit without false output inversion, as long as
the other input is within the Common-Mode Voltage
Range. Their push/pull output structure is capable of
rail-to-rail operation without external pull-up circuitry,
making these devices ideal for interfacing with
CMOS/TTL logic. All inputs and outputs can tolerate a
continuous short-circuit fault condition to either supply.
The comparator’s internal hysteresis ensures clean output switching, even with slow-moving input signals.

MAX976/MAX978/MAX998
Single/Dual/Quad, SOT23, Single-Supply,
High-Speed, Low-Power Comparators
Hysteresis
High-speed comparators can oscillate in the linear
operating region because of noise or undesired parasitic feedback. This tends to occur when the voltage on
one input is equal to or very close to the voltage on the
other input. The MAX976/MAX978/MAX998 have internal hysteresis to counter parasitic effects and noise.
The hysteresis in a comparator creates two trip points:
one for the rising input voltage and one for the falling
input voltage (Figure 1). The difference between the trip
points is the hysteresis. When the comparator input
voltages are equal, the hysteresis effectively causes
one comparator input voltage to move quickly past the
other, taking the input out of the region where oscillation occurs.
Figure 1 illustrates the case where IN- has a fixed voltage applied and IN+ is varied. If the inputs were
reversed, the figure would be the same, except with an
inverted output.
Input-Stage Circuitry
The MAX976/MAX978/MAX998 input common-mode
voltage range is from -0.2V to (VCC - 1.2V). The voltage
range for each comparator input extends to both VCC
and GND. The output remains in the correct logic state
while one or both of the inputs are within the commonmode range. If both input levels are out of the commonmode range, input-stage current saturation occurs, and
the output becomes unpredictable.
Shutdown Mode
The MAX998 features a low-power shutdown mode,
which is activated by forcing SHDN low. Shutdown
mode reduces the supply current to 1nA (typical), disables the comparator, and places the output in a highimpedance state. Drive SHDN high to enable the
comparator. Do not leave SHDN unconnected. Since it
is a high-impedance input, leaving SHDN unconnected
could result in indeterminate logic levels, adversely

affecting comparator operation. Likewise, do not threestate SHDN. Due to the output leakage currents of
three-state devices and the small internal current for
SHDN, three-stating this pin could also result in indeterminate logic levels.
The maximum input voltage for SHDN is 6V, referred to
GND, and is not limited by VCC. This allows the use of
5V logic to drive SHDN while VCC operates at a lower
voltage, such as 3V. The logic threshold limits for
SHDN are proportional to V CC (see Electrical
Characteristics).
_____________Applications Information
Circuit Layout and Bypassing
The MAX976/MAX978/MAX998 have a high-gain bandwidth and require careful board layout. We recommend
the following design guidelines:
1) Use a printed circuit board with an unbroken, lowinductance ground plane. Surface-mount components are recommended.
2) Place a decoupling capacitor (a 0.1µF ceramic
capacitor is a good choice) between V CC and
ground as close to the pins as possible.
3) Keep lead lengths short on the inputs and outputs
to avoid unwanted parasitic feedback around the
comparators.
4) Solder the devices directly to the printed circuit
board instead of using a socket.
5) Minimize input impedance.
6) For slowly varying inputs, use a small capacitor
(~1000pF) across the inputs to improve stability.
Additional Hysteresis
Generate additional hysteresis with three resistors
using positive feedback, as shown in Figure 2. This
positive feedback method slows the hysteresis
response time. Calculate resistor values as follows:
1) Select R3. The leakage current of IN+ is typically
75nA, so the current through R3 should be at least
1.0µA to minimize errors caused by leakage current.
The current through R3 at the trip point is (VREF VOUT) / R3. Consider the two possible output states
when solving for R3. The two formulas are:
R3 = VREF / 1.0µA
or
R3 = (VCC - VREF) / 1.0µA
Use the smaller of the two resulting resistor values.
For example, if VREF = 1.2V and VCC = 5.0V, the two
resistor values are 1.2MΩ and 3.8MΩ. Choose a
standard value for R3 of 1.2MΩ.

2) Choose the hysteresis band required (VHB). For this
example, choose 100mV.
3) Calculate R1. R1 = R3 x (VHB / VCC). Plugging in the
values for this example,
R1 = 1.2MΩ x (100mV / 5.0V) = 24kΩ
4) Choose the trip point for V IN rising. This is the
threshold voltage at which the comparator switches
from low to high as VIN rises above the trip point. In
this example, choose 3.0V.
5) Calculate R2 as follows:

The MAX976 is ideal for making a window detector
(undervoltage/overvoltage detector). The schematic
shown in Figure 3 uses a MAX6120 reference and component values selected for a 2.0V undervoltage threshold and a 2.5V overvoltage threshold. Choose different
thresholds by changing the values of R1, R2, and R3.
OUTA provides an active-low undervoltage indication,
and OUTB gives an active-low overvoltage indication.
ANDing the two outputs provides an active-high,
power-good signal. The design procedure is as follows:
1) Select R1. The leakage current into INB- is normally
75nA, so the current through R1 should exceed
1.0µA for the thresholds to be accurate. R1 values in
the 50kΩ to 100kΩ range are typical.
2) Choose the overvoltage threshold (VOTH) when VIN
is rising, and calculate R2 and R3 with the following
formula:
RSUM = R2 + R3 = R1 x [VOTH / (VREF + VH) - 1]
where VH = 1/2VHYST.
3) Choose the undervoltage threshold (VUTH) when VIN
is falling, and calculate R2 with the following formula:
R2 = (R1 + RSUM) x [(VREF - VH) / VUTH] - R1
where VH = 1/2VHYST.
4) Calculate R3 with the following formula:
R3 = (RSUM) - R2
5) Verify the resistor values. The equations are as follows:

Choose a standard value for R2 of 16kΩ.
6) Verify the trip voltage and hysteresis as follows:

The Typical Operating Circuit shows an application using
the MAX998 as an infrared receiver. The infrared photodiode creates a current relative to the amount of infrared
light present. This current creates a voltage across RD.
When this voltage level crosses the voltage applied by the
voltage divider to the inverting input, the output transitions.
