LM339DT Datasheet, PDF (1/16 Pages) STMicroelectronics – Low-power quad voltage comparators

LM139, LM239, LM339
Low-power quad voltage comparators
Features
■ Wide single supply voltage range or dual
supplies for all devices: +2 to +36 V or ±1 V to
±18 V
■ Very low supply current (1.1 mA) independent
of supply voltage
■ Low input bias current: 25 nA typ
■ Low input offset current: ±5 nA typ
■ Low input offset voltage: ±1 mV typ
■ Input common-mode voltage range includes
ground
■ Low output saturation voltage: 250 mV typ;
(I_SINK = 4 mA)
■ Differential input voltage range equal to the
supply voltage
■ TTL, DTL, ECL, MOS, CMOS compatible
outputs
Description
This family of devices consists of four
independent precision-voltage comparators with
an offset voltage specification as low as 2 mV
maximum for LM339A, LM239A and LM139A.
Each comparator has been designed specifically
to operate from a single power 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.
