Part Description: MAX9021 2 4 DS

Part Details:

19-1842; Rev 2; 1/07 Micropower, Ultra-Small, Single/Dual/Quad, Single-Supply Comparators MAX9021/MAX9022/MAX9024 General Description Features The MAX9021/MAX9022/MAX9024 single/dual/quad Low-Cost Solution Available in Space-Saving comparators are optimized for low-power consumption SC70 Packages (Half the Size of SOT23) while still providing a fast output response. They aredesigned for single-supply applications from 2.5V to Low 2.8µA Supply Current 5.5V, but can also operate from dual supplies. These 3µs Propagation Delay comparators have a 3µs propagation delay and con-sume 2.8µA of supply current per comparator over the Internal 4mV Comparator Hysteresis -40°C to +125°C operating temperature range. The Comparator Output Swings Rail-to-Rail combination of low-power, single-supply operationdown to 2.5V, and ultra-small footprint makes these 2.5 to 5.5V Single-Supply Voltage Range devices ideal for portable applications. No Phase Reversal for Overdriven Inputs The MAX9021/MAX9022/MAX9024 have 4mV of built-in hysteresis to provide noise immunity and prevent oscil- Space-Saving Packages lations even with a slow-moving input signal. The input 5-Pin SC70 (MAX9021) common-mode range extends from the negative supply 8-Pin SOT23 (MAX9022) to within 1.1V of the positive supply. The design of the 8-Pin µMAX (MAX9022) comparator-output stage substantially reduces switch- 14-Pin TSSOP (MAX9024) ing current during output transitions, eliminating power-supply glitches. Ordering Information The MAX9021 single comparator is available in tiny 5-pin SC70 and SOT23 packages. The MAX9022 dual PIN- PKG comparator is available in 8-pin SOT23, µMAX®, and PA RT TEMP RANGE PACKAGE CODE SO packages, and the MAX9024 quad comparator isavailable in 14-pin TSSOP and SO packages.
