Product Summary

The LM2901 is a low power quad voltage comparator. The comparator LM2901 is designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. The comparator LM2901 also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

Parametrics

LM2901 absolute maximum ratings: (1)VCC Supply Voltage: ±18 to 36 V; (2)Vid Differential Input Voltage: ±36 V; (3)VI Input Voltage: -0.3 to +36 V; (4)Tstg Storage Temperature Range: -65 to +150 ℃; (5)Tj Junction Temperature: +150 ℃.

Features

LM2901 features: (1)Wide single supply voltage range or dual supplies for all devices : +2V TO +36V OR ±1V TO ±18V; (2)Very low supply current (1.1ma) independent of supply voltage (1.4mW/comparator at +5V); (3)Low input bias current: 25nA TYP; (4)Low input offset current: ±5nA TYP; (5)Input common-mode voltage range includes ground; (6)Low output saturatiovoltage: 250mV TYP. (IO = 4mA); (7)Differential input voltage range equal to the supply voltage; (8)TTL, DTL, ECL, MOS, CMOS compatible outputs.
