Low power quad voltage comparator

STMicroelectronics 

LM2901

Low power quad voltage comparator

Features

■ Wide single supply voltage range or dual

supplies for all devices: +2V to +36V or ±1V to

±18V

■ Very low supply current (1.1mA) independent

of supply voltage (1.4mW/comparator at +5V)

■ Low input bias current: 25nA typ.

■ Low input offset current: ±5nA typ.

■ Input common-mode voltage range includes

negative rail

■ Low output saturation voltage:

250mV typ. (IO = 4mA)

■ 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. All these comparators 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.
