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 V
DC 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
