Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators
General DescriptionThe MAX9030/MAX9031/MAX9032/MAX9034 single/
dual/quad comparators are optimized for single-supply
applications from +2.5V to +5.5V but can also be oper-
ated from dual supplies. These comparators have a
188ns propagation delay and consume 35µA of supply
current per comparator over the -40°C to +125°C oper-
ating temperature range. The combination of low-
power, single-supply operation down to +2.5V, and
ultra-small footprint makes these devices ideal for
portable applications.
The MAX9030 is a low-cost single comparator with
shutdown. The MAX9031, MAX9032, and MAX9034 are
low-cost single, dual, and quad comparators without
shutdown, respectively. The comparators’ 4mV of built-
in hysteresis provides noise immunity and prevents
oscillations even with a slow-moving input signal. The
input common-mode range extends from the negative
supply to within 1.1V of the positive supply. The design
of the comparator output stage substantially reduces
switching current during output transitions, virtually
eliminating power-supply glitches.
The MAX9030 single comparator with shutdown is avail-
able in the space-saving 6-pin SC70 and SOT23 pack-
ages. The MAX9031 single comparator is available in tiny
5-pin SC70 and SOT23 packages. The MAX9032 dual
comparator is available in 8-pin SOT23 and µMAX pack-
ages, and the MAX9034 quad comparator is available in
a 14-pin TSSOP package.

MAX9030/MAX9031/MAX9032/MAX9034
Detailed DescriptionThe MAX9030/MAX9031/MAX9032/MAX9034 are sin-
gle/dual/quad low-cost comparators. They have an
operating supply voltage from +2.5V to +5.5V when
operating from a single supply and from ±1.25V to
±2.75V when operating from dual power supplies, and
consume only 35µA. Their common-mode input voltage
range extends from the negative supply to within 1.1V
of the positive supply. Internal hysteresis ensures clean
output switching, even with slow-moving input signals.
Shutdown ModeThe MAX9030 comparator comes with a power-saving
shutdown mode. When in shutdown, the supply current
drops from a typical 35µA to 0.05µA, and the outputs
become high impedance. SHDNhas a high input imped-
ance and typically draws 0.1µA when connected to VSS
or VDD. A maximum logic low voltage of 0.3V ✕ VDD
applied to SHDNplaces the device in the shutdown
mode. A minimum logic high voltage of 0.7V ✕ VDD
applied to SHDNwill enable normal operation. To dis-
able shutdown, connect SHDNto VDD.
Applications Information
Adding HysteresisHysteresis extends the comparator’s noise margin by
increasing the upper threshold and decreasing the
lower threshold. A voltage-divider from the output of the
comparator sets the trip voltage. Therefore, the trip volt-
age is related to the output voltage.
These comparators have 4mV internal hysteresis.
Additional hysteresis can be generated with two resis-
tors using positive feedback (Figure 1). Use the follow-
ing procedure to calculate resistor values:
