• Description: Low Power Dual Voltage Comparator
• Manufacturer: NXP Semiconductors

characteristic in that the input common-mode voltage range includes
Philips Semiconductors
DESCRIPTION
The AU2903 consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0 mV
max. for two comparators 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
ground, even though operated from a single power supply voltage.
