Very low supply current: 0.1 mA/comparator
independent of supply voltage
Extremely low input bias current: 1 pA typ
Extremely low input offset currents: 1 pA typ
Low input offset voltage
Input common-mode voltage range includes
GND
Low output saturation voltage 150 mV typical
Output compatible with TTL, MOS and CMOS
High input impedance: 10
12
Ω typical
Fast response time: 200 ns typ for TTL level
input step
Applications
Battery powered electronics
General-purpose portable device
General-purpose low voltage application
Description
These devices consist of two independent
precision voltage comparators, designed to
operate with single or dual supplies.
These differential comparators use the
STMicroelectronics silicon lin MOS process giving
them an excellent consumption-speed ratio.
These devices are ideally suited for low
consumption applications.
