NCS3402 D

NCS3402
Dual Nano-power Open
Drain Output Comparator
The NCS3402 is a nano−power comparator consuming only 470 nA
per channel supply current, which make this device ideal for battery
power and wireless handset applications.
The NCS3402 has a minimum operating supply voltage of 2.7 V
over the extended industrial temperature range (TA = −40°C to 125°C),
while having an input common−mode range of −0.1 to VDD + 5 V.
The ultra low supply current makes the NCS3402 an ideal choice for
battery powered and portable applications where quiescent current is
the primary concern. Reverse battery protection guards the amplifier
from an over−current condition due to improper battery installation.
For harsh environments, the inputs can be taken 5 V above the positive
supply rail without damage to the device.
• Low Supply Current: 470 nA/Per Channel
Input Common−Mode Range exceeds the rails
−0.1 V to VDD + 5 V
Supply Voltage Range: 2.7 V to 16 V
Reverse Battery Protection Up to 18 V
