LM2901H
High Temperature Low Power Quad Voltage Comparators
■ Wide single supply voltage range or dual
supplies for all devices: +2V to +36V or ±1V to
±18V
■ Very low supply current (1.1mA) independent
of supply voltage (1.4mW/comparator at +5V)
■ Low input bias current: 25nA typ.
■ Low input offset current: ±5nA typ.
■ Input common-mode voltage range includes
ground
■ Low output saturation voltage:
250mV typ. (I
O
= 4mA)
■ Differential input voltage range equal to the
supply voltage
■ TTL, DTL, ECL, MOS, CMOS compatible
outputs
Description
This device consists of four independent precision
voltage comparators. All these comparators were
designed specifically to operate from a single
power 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.
