• Manufacturer Part Number: ncs5650
• Description: Ncs5650 2 Amp Plc Line Driver
• Manufacturer: ON Semiconductor

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.
PIN DESCRIPTION
1. The principal purpose of pin 2 is to facilitate the implementation of the 4th−order lowpass filter when operating on single−sided supply

by providing a virtual common at mid−supply. When operating on dual balanced supplies, Pin 2 must be left floating and the external
common of the dual supplies should be used for the filter implementation.
