LM2479

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. The IC is packaged in an industry

standard 8 lead molded DIP package.
