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. (IO = 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.
