LM2481 - 145V Triple Bias Clamp

Description

The LM2481 driver is an Integrated 145V 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 -20.
