LM2485 General Description

The LM2485 is a triple channel clamp amplifier used to DC restore the AC coupled outputs of a DTV CRT driver and for cut-off adjustment. The LM2485 also has an integrated blanking amplifier that can be used to drive the G1 grid of a CRT negative for vertical retrace blanking. The blanking output has.
