www.DataSheet4U.com AS1970 - AS1975 L o w - Vo l ta g e S i n g l e / D u a l / Q u a d C o m pa r a t o r s D a ta S he e t 1 General Description The AS1970 - AS1975 are single/dual/quad comparators that operate with supplies from 2.5 to 5.5V making them perfect for all 3- and 5-volt applications. The comparators can also operate with dual supplies (±1.25 to ±2.75V), and require very little supply current (down to 8.5µA) with minimal propagation delay (300ns). Low input bias current (1.0pA, typ), low input offset voltage (0.5mV, typ), and internal hysteresis (3mV) make these comparators ideal for low-power single-cell applications including power-management and power-monitoring systems. The comparators are available as the standard products listed in Table 1. Table 1. Standard Products Model AS1970/AS1972/AS1974 AS1971/AS1973/AS1975 Output Type Push/Pull Open-Drain 2 Key Features !
