AS1970 - AS1975 Low-Voltage Single/Dual/Quad Comparators

Data Sheet
1 General Description
2 Key Features

The AS1970 - AS1975 are single/dual/quad comparators that operate with supplies from to 5.5V making them perfect for all 3- and 5-volt applications. The comparators can also operate with dual supplies to
lid ±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 volt-
a age 0.5mV, typ , and internal hysteresis 3mV make
these comparators ideal for low-power single-cell appli-
v cations including power-management and power-moni-
toring systems.
