General Description
____________________________Features
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 ±±.25V to ±2.ꢀ5V
dual supplies. They consume only ±±µA of supply cur-
rent while achieving a 300ns propagation delay.
o 11µA Quiescent Supply Current
o 2.5V to 5.5V Single-Supply Operation
o Common-Mode Input Voltage Range Extends
250mV Beyond the Rails
o 300ns Propagation Delay
o Push-Pull Output Stage Sinks and Sources
8mA Current (MAX985/MAX989/MAX993)
Input bias current is typically ±.0pA, and input offset
voltage is typically 0.5mV. Internal hysteresis ensures
clean output switching, even with slow-moving input
signals.
o Open-Drain Output Voltage Extends Beyond V
CC
(MAX986/MAX990/MAX994)
o Unique Output Stage Reduces Output Switching
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 inter-
nal 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
Current, Minimizing Overall Power Consumption
o 80µA Supply Current at 1MHz Switching

o No Phase Reversal for Overdriven Inputs

Ordering Information
The single MAX985 is available in a chip-scale pack-
age (UCSP™), significantly reducing the required PC
board area. The single MAX985/MAX986 are available
in 5-pin SCꢀ0 packages and the dual MAX989/MAX990
are available in 8-pin SOT23 packages.

V
CC
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 ±±µA.
Their common-mode input voltage range extends 0.25V
beyond each rail. Internal hysteresis ensures clean out-
put switching, even with slow-moving input signals.
Large internal output drivers allow rail-to-rail output
swing with up to 8mA loads.

The MAX985/MAX989/MAX993 have ±3mV internal

three resistors using positive feedback (Figure ±).

ate at any differential input voltage within these limits.
Input bias current is typically ±.0pA if the input voltage
is between the supply rails. Comparator inputs are pro-
tected from overvoltage by internal body diodes con-
nected to the supply rails. As the input voltage exceeds
the supply rails, these body diodes become forward
biased and begin to conduct. Consequently, bias cur-
rents increase exponentially as the input voltage
exceeds the supply rails.

the current through R3 should be at least ±µA to
minimize errors caused by leakage current. The cur-
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 oper-
ation. 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 out-
put switching frequency approaches ±MHz. This char-
acteristic eliminates the need for power-supply filter
capacitors to reduce glitches created by comparator
switching currents. Another advantage realized in high-
speed, battery-powered applications is a substantial
increase in battery life.

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 hys-
teresis can be generated using positive feedback, but
the formulas differ slightly from those of the
MAX985/MAX989/MAX993.

Board Layout and Bypassing

Power-supply bypass capacitors are not typically need-
ed, but use ±00nF 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.

UCSP Applications Information
Figure 3 shows a zero-crossing detector application.
For the latest application details on UCSP construction,
dimensions, tape carrier information, PCB techniques,
bump-pad layout, and recommended reflow tempera-
ture profile, as well as the latest information on reliability
testing results, refer to the Application Note: UCSP—A
Wafer-Level Chip-Scale Package on Maxim’s web site
at www.maxim-ic.com/ucsp.
The MAX985’s inverting input is connected to ground,
and its noninverting input is connected to a ±00mV
P-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 lev-
els 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
V
CC
and the 5V supply to the pullup resistor.
