NTE834 & NTE834SM
Integrated Circuit
Low Power Low Offset Voltage Comparator
Description:
The NTE834 and NTE834SM are precision voltage comparators designed 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 has a unique characteristic in that the input common鈥搈ode voltage range
includes GND, even though operated from a single power supply voltage.
