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.
