低功耗四电压比较器 LOW POWER QUAD VOLTAGE COMPARATORS

Description

This device consists of four independent precision voltage comparators. All these comparators were 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 ground even though operated from a single power supply voltage

■ 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 ground

■ Low output saturation voltage: 250mV typ. IO= 4mA

■ Differential input voltage range equal to the supply voltage

■ TTL, DTL, ECL, MOS, CMOS compatible outputs
