1
Vin
Positive power supply input voltage
2
GND
Power supply ground
3
Enable
This input is used to place the device into low−power stand by. When this input is pulled low, the
device is disabled. If this function is not used, Enable should be connected to Vin.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
