LM2903H中文资料低功耗双电压比较器数据手册ST规格书

描述 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.

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.

特性 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 of supply voltage (1 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
