LM2903W

Low-power dual voltage comparator

Preliminary data

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

SO-8

of supply voltage (1 mW/comparator at +5 V)

■ Low input bias current: 25 nA typ.

■ Low input offset current: 5 nA typ.

(Plastic micropackage)

■ Input common-mode voltage range includes

negative rail

■ Low output saturation voltage:

250 mV typ. (I = 4 mA)

Pin connections (top view)

■ Differential input voltage range equal to the

supply voltage

■ TTL, DTL, ECL, MOS, CMOS compatible

outputs

■ ESD internal protection: 2 kV

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.

1 - Output 1

2 - Inverting input 1

The input common-mode voltage range includes

the negative rail even though operated from a

single power supply voltage.

3 - Non-inverting input 1

4 - V

5 - Non-inverting input 2

6 - Inverting input 2

All the pins are protected against electrostatic

discharge up to 2 kV. As a consequence, the input

7 - Output 2

voltages must not exceed the magnitude of V

8 - V

or V
