LM2901Q4T Datasheet, PDF (1/17 Pages) STMicroelectronics – Low-power quad voltage comparator

LM2901
Low-power quad voltage comparator
Features
■ Wide single supply voltage range or dual
supplies for all devices: +2 V to +36 V or ±1 V
to ±18 V
■ Very low supply current (1.1 mA) independent
of supply voltage (1.4 mW/comparator at +5 V)
■ Low input bias current: 25 nA typ.
■ Low input offset current: ±5 nA typ.
■ Input common-mode voltage range includes
negative rail
■ Low output saturation voltage:
250 mV typ. (I_O = 4 mA)
■ Differential input voltage range equal to the
supply voltage
■ TTL, DTL, ECL, MOS, CMOS compatible
outputs
Description
This device consists of four independent precision
voltage comparators, which are 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 the negative rail even
though operated from a single power supply
voltage.
