1 / 11 page 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 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. ________________________Applications Features o Low-Cost Solution Available in Space-Saving SC70 Packages (MAX9030/MAX9031) o +2.5 to +5.5V Single-Supply Voltage Range o Comparator Output Swings Rail-to-Rail® o Internal 4mV Comparator Hysteresis o 188ns Propagation Delay o Low 35µA Supply Current o No Phase Reversal for Overdriven Inputs o Space-Saving Packages 5-Pin SC70 (MAX9031) 6-Pin SC70 (MAX9030) 8-Pin SOT23 (MAX9032) 14-Pin TSSOP (MAX9034) Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators ________________________________________________________________ Maxim Integrated Products 1 TOP VIEW VSS OUT IN- 15 VDD IN+ MAX9031 SC70-5/SOT23-5 2 34 INB- INB+ VSS 1 2 8 7 VDD OUTB INA- INA+ OUTA SOT23-8/ µMAX-8/ SO-8 3 4 6 5 MAX9032 14 13 12 11 10 9 8 1 2 3 4 5 6 7 OUTD IND- IND+ VSS VDD INA+ INA- OUTA MAX9034 INC+ INC- OUTC OUTB INB- INB+ TSSOP-14/SO-14 VSS OUT IN- 16 VDD 5 IN+ MAX9030 SC70-6/SOT23-6 2 34 SHDN Pin Configurations 19-1767; Rev 0; 10/00 Ordering Information *Future product–contact factory for availability.
