Maxim MAX9141 40ns, low-power, 3v/5v, rail-to-rail single-supply comparator Datasheet

19-2064; Rev 3; 1/10
40ns, Low-Power, 3V/5V, Rail-to-Rail
Single-Supply Comparators
The MAX9140/MAX9141 are single and the MAX9142/
MAX9144 are dual/quad high-speed comparators optimized for systems powered from a 3V or 5V supply. The
MAX9141 features latch enable and device shutdown.
These devices combine high speed, low power, and
rail-to-rail inputs. Propagation delay is 40ns, while supply current is only 150µA per comparator.
The input common-mode range of the MAX9140/
MAX9141/MAX9142/MAX9144 extends beyond both
power-supply rails. The outputs pull to within 0.3V of
either supply rail without external pullup circuitry, making these devices ideal for interface with both CMOS
and TTL logic. All input and output pins can tolerate a
continuous short-circuit fault condition to either rail.
Internal hysteresis ensures clean output switching, even
with slow-moving input signals.
The MAX9140/MAX9141/MAX9142/MAX9144 are higher-speed, lower-power, and lower-cost upgrades to
industry-standard comparators MAX941/MAX942/
MAX944.
The MAX9140 are offered in tiny 5-pin SC70 and SOT23
packages. The MAX9141 and MAX9142 are available in
8-pin SOT23 and SO packages, while the MAX9144 is
available in both 14-pin SO and TSSOP packages.

Note 1: All devices are 100% production tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 2: Inferred from PSRR test.
Note 3: Inferred from CMRR test. Note also that either or both inputs can be driven to the absolute maximum limit (0.3V beyond either
supply rail) without damage or false output inversion.
Note 4: VOS is defined as the center of the input-referred hysteresis zone. See Figure 1.
Note 5: The input-referred trip points are the extremities of the differential input voltage required to make the comparator output
change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis
zone. See Figure 1.
Note 6: The polarity of IB reverses direction as VCM approaches either supply rail.
Note 7: Specified over the full common-mode voltage range (VCMR).
Note 8: Specification is for current flowing into or out of the output pin for VOUT driven to any voltage from VCC to GND while the part is
in shutdown.
Note 9: Specified between any two channels in the MAX9142/MAX9144.
Note 10: Specified as the difference between tPD+ and tPD- for any one comparator.
Note 11: Applies to the MAX9141 only for both SHDN and LE.
Note 12: Applies to the MAX9141 only. Comparator is active with LE driven high and is latched with LE driven low (VOD = 10mV). See
Figure 2.
Note 13: Applicable to the MAX9141 only. Comparator is active with the SHDN driven high and is shutdown with SHDN driven low.
Shutdown enable time is the delay when the SHDN is driven high to the time the output is valid. Shutdown disable time is the
delay when the SHDN is driven low to the time the comparator shuts down.

40ns, Low-Power, 3V/5V, Rail-to-Rail
Single-Supply Comparators
The MAX9140/MAX9141/MAX9142/MAX9144 singlesupply comparators feature internal hysteresis, high
speed, and low power. Their outputs are pulled to within 300mV of either supply rail without external pullup or
pulldown circuitry. Rail-to-rail input voltage range and
low-voltage single-supply operation make these
devices ideal for portable equipment. The
MAX9140/MAX9141/MAX9142/MAX9144 interface
directly to CMOS and TTL logic.
Most high-speed comparators oscillate in the linear
region because of noise or undesired parasitic feedback. This tends to occur when the voltage on one
input is at or equal to the voltage on the other input. To
counter the parasitic effects and noise, the MAX9140/
MAX9141/MAX9142/MAX9144 have an internal hysteresis of 1.5mV.
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. The average of the trip points is
the offset voltage. When the comparator’s input voltages are equal, the hysteresis effectively causes one
comparator input voltage to move quickly past the
other, thus taking the input out of the region where
oscillation occurs. Standard comparators require hysteresis to be added with external resistors. The
MAX9140/MAX9141/MAX9142/MAX9144’s fixed internal
hysteresis eliminates these resistors. To increase hysteresis and noise margin even more, add positive feedback with two resistors as a voltage divider from the
output to the noninverting input.
Figure 1 illustrates the case where IN- is fixed and IN+
is varied. If the inputs were reversed, the figure would
look the same, except the output would be inverted.
The MAX9141 includes an internal latch that allows
—
storage of comparison results. The LE pin has a high
—
input impedance. If LE is high, the latch is transparent
(i.e., the comparator operates as though the latch is not
present). The comparator's output state is latched
—
when LE is pulled low (Figure 2).
Shutdown Mode (MAX9141 Only)
–———–
The MAX9141 shuts down when the SHDN pin is low.
When shut down, the supply current drops to less than
12µA, and the three-state output becomes high imped–———–
ance. The S H D N pin has a high-input impedance.
———–
Connect SHDN to VCC for normal operation. Exit shutdown with L—E high (transparent state); otherwise, the
output will be indeterminate.

Input Stage Circuitry
The MAX9140/MAX9141/MAX9142/MAX9144 include
internal protection circuitry that prevents damage to the
precision input stage from large differential input voltages. This protection circuitry consists of two back-toback diodes between IN+ and IN- as well as two series
4.1kΩ resistors (Figure 3). The diodes limit the differential voltage applied to the internal circuitry of the comparators to be no more than 2VF, where VF is the forward voltage drop of the diode (about 0.7V at +25°C).
For a large differential input voltage (exceeding 2VF),
this protection circuitry increases the input bias current
at IN+ (source) and IN- (sink).
Input Current =
(IN+ - IN-) - 2VF
2 x 4.1kΩ
Input current with large differential input voltages
should not be confused with input bias current (IB). As
long as the differential input voltage is less than 2VF,
this input current is equal to IB. The output is in the correct logic state if one or both inputs are within the common-mode range.

Output Stage Circuitry
The MAX9140/MAX9141/MAX9142/MAX9144 contain a
current-driven output stage as shown in Figure 4.
During an output transition, ISOURCE or ISINK is pushed
or pulled to the output pin. The output source or sink
current is high during the transition, creating a rapid
slew rate. Once the output voltage reaches V OH or
VOL, the source or sink current decreases to a small
value, capable of maintaining the VOH or VOL static
condition. This significant decrease in current conserves power after an output transition has occurred.
One consequence of a current-driven output stage is a
linear dependence between the slew rate and the load
capacitance. A heavy capacitive load will slow down a
voltage output transition. This can be useful in noisesensitive applications where fast edges may cause
interference.

Applications Information
Circuit Layout and Bypassing
The high-gain bandwidth of the MAX9140/MAX9141/
MAX9142/MAX9144 requires design precautions to
realize the full high-speed capabilities of these comparators. The recommended precautions are:
1) Use a PCB with a good, 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) Pay close attention to the decoupling capacitor’s
bandwidth, keeping leads short.
4) On the inputs and outputs, keep lead lengths
short to avoid unwanted parasitic feedback
around the comparators.
5) Solder the device directly to the PCB instead of
using a socket.
