Micropower, Low-Voltage, UCSP/SC70,
Rail-to-Rail I/O Comparators
General Description
The MAX985/MAX986/MAX989/MAX990/MAX993/
MAX994 single/dual/quad micropower comparators
feature low-voltage operation and rail-to-rail inputs and
outputs. Their operating voltages range 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 11µA of supply current while achieving a 300ns 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.
The output stage’s unique design limits supply-current
surges while switching, virtually eliminating the supply
glitches typical of many other comparators. The
MAX985/MAX989/MAX993 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 MAX986/MAX990/MAX994 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 singleended converters.
The single MAX985 is available in a chip-scale package (UCSP™), significantly reducing the required PC
board area. The single MAX985/MAX986 are available
in 5-pin SC70 packages and the dual MAX989/MAX990
are available in 8-pin SOT23 packages.

_______________Detailed Description
The MAX985/MAX986/MAX989/MAX990/MAX993/
MAX994 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 11µA.
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 MAX985/MAX989/MAX993 have a
push-pull output structure that sinks as well as sources
current. The MAX986/MAX990/MAX994 have an opendrain 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
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. Another advantage realized in highspeed, battery-powered applications is a substantial
increase in battery life.

__________Applications Information
Additional Hysteresis
MAX985/MAX989/MAX993
The MAX985/MAX989/MAX993 have ±3mV 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 MAX985/MAX989/MAX993.
1) Select R3. Leakage current at IN is under 10nA, so
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 in
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.

8.2kΩ standard value:

Use the following procedure to calculate resistor
values:
1) Select R3 according to the formulas R3 = VREF /
500µA or R3 = (VREF - VCC) / 500µA - 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 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.
5) Calculate R2 as follows:
R2 =
Hysteresis = VTHR − VTHF
MAX986/MAX990/MAX994
The MAX986/MAX990/MAX994 have ±3mV internal
hysteresis. They have open-drain outputs and require
an external pullup resistor (Figure 2). Additional hysteresis can be generated using positive feedback, but
the formulas differ slightly from those of the
MAX985/MAX989/MAX993.

Power-supply bypass capacitors are not typically needed, but use 100nF bypass capacitors when supply
impedance is high, when supply leads are long,
or when excessive noise is expected on the supply
lines. Minimize signal trace lengths to reduce stray
capacitance.

Figure 3 shows a zero-crossing detector application.
The MAX985’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 MAX986 is powered by the 5V
supply voltage, and the pullup resistor for the MAX986’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.
