MAX9030/MAX9031/ MAX9032/MAX9034
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 operated 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 temperature range. The combination of low-power, singlesupply 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 lowcost 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.
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® packages, and the MAX9034 quad comparator is available in a 14-pin TSSOP package.
