19-0450; Rev 0; 11/95 Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators _______________General Description ____________________________Features The MAX971–MAX974 and MAX981–MAX984 single/ µMAX Package—Smallest 8-Pin SO dual/quad low-voltage comparators feature the lowest (MAX9_1/MAX9_2/MAX9_3) power consumption available. These micropower Ultra-Low 4µA Max Quiescent Current devices draw less than 4µA supply current over temperature (MAX971/MAX972, MAX981/MAX982), and Over Extended Temp. Range (MAX971/MAX981) include an internal 1.182V ±1% (MAX971/MAX973/ Power Supplies: Single +2.5V to +11V MAX974) or ±2% (MAX981–MAX984) voltage reference Dual ±1.25V to ±5.5V and programmable hysteresis. Input Voltage Range Includes Negative Supply Ideal for 3V or 5V single
