LM2901Q4T Description
This gadget is made up of four separate, precise voltage comparators that work independently and were created specifically to work with a single supply and a variety of voltages. It is also feasible to operate using separate power supplies.
The input common-mode voltage range of these comparators includes the negative rail despite being powered by a single power supply voltage, which is another distinctive feature.
LM2901Q4T 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
