Low-Cost, Ultra-Small, Single/Dual/Quad
Single-Supply Comparators
General Description
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 oper-
ated from dual supplies. These comparators have a
188ns propagation delay and consume 35碌A of supply
current per comparator over the -40掳C to +125掳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鈥?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 碌MAX pack-
ages, and the MAX9034 quad comparator is available in
a 14-pin TSSOP package.
