LM2483

LM2483 180V Triple Bias Clamp November 2002 LM2483 180V Triple Bias Clamp General Description The LM2483 driver is an Integrated 180V triple bias clamp circuit for DC recovery of each of the AC coupled outputs of a HDTV CRT driver. It is well matched with the DAC outputs of the LM126X family of pre-amplifiers. Each amplifier has its gain internally set to -30. The LM2483 is packaged in an industry standard 14 lead molded plastic dual-in-line package. n Matched to LM2426 HDTV Driver Applications n AC coupled HDTV applications using the 1080i and 720p formats as well as standard NTSC and PAL formats.
