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 pack-
age.
