LM2901Q4T [STMicroelectronics]

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
