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.
