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.

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
