LOWPOWER DUAL VOLTAGE COMPARATORS


LM293 Datasheet Preview


LM193, LM293, LM393
Low-power, dual-voltage comparators
Datasheet - production data
Description
The LM193, LM293, and LM393 devices consist
of two independent low voltage comparators
designed specifically to operate from a single
supply over a wide range of voltages. Operation
from split power supplies is also possible.
These comparators also have a unique
characteristic in that the input common-mode
voltage range includes ground even though
operated from a single power supply voltage.
Features
Wide single-supply voltage range or dual
supplies: 2 V to 36 V or ±1 V to ±18 V
Very low supply current (0.45 mA)
independent of supply voltage
(1 mW/comparator at 5 V)
Low input bias current: 20 nA typ.
Low input offset current: ±3 nA typ.
Low input offset voltage: ±1 mV typ.
Input common-mode voltage range includes
ground
Low output saturation voltage: 80 mV typ.
(Isink = 4 mA)
Differential input voltage range equal to the
supply voltage
TTL, DTL, ECL, MOS, CMOS compatible
outputs
Available in DFN8 2x2, MiniSO8, TSSOP8,
and SO8 packages
