ST LM2901Q4T

通用CMOS，DTL，MOS，开路集电极，TTL

Overview

This device consists of four independent precision voltage comparators, which 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: +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 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

Applications

• Power Management

• Consumer Electronics

• Portable Devices

• Industrial
