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.
ill The comparators are available as the standard products
listed in Table

The AS1970/AS1972/AS1974 push/pull output can sink
s n or source current. e The AS1971/AS1973/AS1975 open-drain output can be m t pulled beyond VCC to a maximum of 5.5V > VEE. These
open-drain versions are ideal for logic-level translators or bipolar-to-unipolar converters.
a n Large internal output drivers allow Rail-to-Rail output o3 Applications swings with loads of up to 8mA.

The AS1970/AS1971 are available in a 5-pin SOT23
c package. The AS1972/AS1973 are available in a 8-pin

MSOP package. The AS1974/AS1975 are available in a
l 14-pin TSSOP package.
