MAX9030/MAX9031/
MAX9032/MAX9034
Low-Cost, Ultra-Small, Single/Dual/Quad
Single-Supply Comparators
General Description
Features
● Low-Cost Solution Available in Space-Saving SC70
The MAX9030/MAX9031/MAX9032/MAX9034 single/
dual/quad comparators are optimized for single-supply
applications from +2.5V to +5.5V but can also be operat-
ed 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 operating tem-
perature range. The combination of low-power, single-
supply operation down to +2.5V, and ultra-small footprint
makes these devices ideal for portable applications.
Packages (MAX9030/MAX9031)
● +2.5 to +5.5V Single-Supply Voltage Range
● Comparator Output Swings Rail-to-Rail
● Internal 4mV Comparator Hysteresis
● 188ns Propagation Delay
● Low 35μA Supply Current
● No Phase Reversal for Overdriven Inputs
● Space-Saving Packages
• 5-Pin SC70 (MAX9031)
• 6-Pin SC70 (MAX9030)
• 8-Pin SOT23 (MAX9032)
• 14-Pin TSSOP (MAX9034)
The MAX9030 is a low-cost single comparator with shut-
down. 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 available in
the space-saving 6-pin SC70 and SOT23 packages.
