LM2479NA - 120V Triple Bias Clamp

General Description

The LM2479 is an Integrated 120V triple bias clamp circuit for DC recovery of each of the AC coupled outputs of a 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 -18.
