LM2903H Datasheet Low-power Dual Voltage Comparator

Manufacturer: STMicroelectronics

Overview: SO8 TSSOP8 Pin connections (top view) 1 = Output 1 2 = Inverting input 1 3 = Non-inverting input 1 4 = VCC5 = Non-inverting input 2 6 = Inverting input 2 7 = Output 2 8 = VCC+ LM2903H Low-power dual voltage.

General 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.

Key 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.
