LESHAN RADIO COMPANY, LTD.
The LR393 consists of two independent voltage
comparators with an offset voltage specification as low as
2.0mV max. for two comparators which were designed
specifically to operation from a single power supply over a
wide range of voltages. Operate from split power supplies
is also possible,and the low power supply current drain is
independent of the magnitude of the power supply voltage.
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.
z Wide supply voltage range: single supply operation: 2V to 36V, dual supply operation: f1V to f18V
z Very low supply current drain (0.8mA) independent of supply voltage(2.0mW/comparator at 5.0 VDC)
z Low input biasing current: 25nA
z Low input offset current: 5.0nA; Low input offset voltage: 5.0mV
z Input common-mode voltage range includes ground
z Differential input voltage range equal to the power supply voltage
z Output voltage compatible with TTL,DTL,ECL,MOS and CMOS logic systems.
