STMicroelectronics 

LM2903

Low-power dual voltage comparator

Features

■ Wide single supply voltage range or dual

supplies +2 V to +36 V or ±1 V to ±18 V

■ Very low supply current (0.4 mA) independent

of supply voltage (1 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

■ Automotive qualification

Description

This device consists of two independent low-

power voltage comparators designed specifically

to operate from a single supply over a wide range

of voltages. Operation from split power supplies is

also possible.

The device also has a unique characteristic in that

the input common-mode voltage range includes

the negative rail even though operated from a

single power supply voltage.
