LM2901(2012) Datasheet - STMicroelectronics

Description

   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
