Description
The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2.0mV max for each comparator which were designed specifically to operate from a single
power supply o
Features
- Wide single supply voltage range 2.0VDC
to 36VDC or dual supplies ±1.0VDC to ±18VDC.
- Very low supply current drain (0.8mA)
independent of supply voltage (1.0mW/comparator at 5.0VDC).
- Low input biasing current 25nA.
- Low input offset current and offset voltage.
- Input common-mode voltage range
includes ground.
- Differential input voltage range equal to the
power supply voltage.
- Low output 250mV at 4mA saturation
voltage.
- Output.
