AU2901

DESCRIPTION

The AU2901 consists of four independent precision voltage

comparators, with an offset voltage specification as low as 2.0 mV

max for each comparator, which were designed specifically to

operate from a single power supply over a wide range of voltages.

Operation from split power supplies is also possible and the low

power supply current drain is independent of the magnitude of the

power supply voltage. These comparators also have a unique

characteristic in that the input common-mode voltage range includes

ground, even though they are operated from a single power supply

voltage.

The AU2901 was designed to directly interface with TTL and CMOS.

When operated from both plus and minus power supplies, the

AU2901 will directly interface with MOS logic where their low power

drain is a distinct advantage over standard comparators.

FEATURES

• Wide single supply voltage range 2.0 VDC to 36 VDC or dual

supplies ±1.0 VDC to ±18 VDC

• Very low supply current drain (0.8 mA) independent of supply

voltage (1.0 mW/comparator at 5.0 VDC)

• Low input biasing current 25 nA

• Low input offset current ±5 nA and offset voltage

• Input common-mode voltage range includes ground

• Differential input voltage range equal to the power supply voltage

• Low output 250 mV at 4 mA saturation voltage

• Output voltage compatible with TTL, DTL, ECL, MOS and CMOS

logic systems

APPLICATIONS

• A/D converters

• Wide range VCO

• MOS clock generator

• High voltage logic gate

• Multivibrators
