高温低功耗四电压比较器 High temperature low power quad voltage comparators

Description

This device consists of four independent precision voltage comparators. All these comparators are designed specifically to operate from a single power 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 ground even though operated from a single power supply voltage.

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 ground

■ 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
