LM2480
80V Triple Bias Clamp
General Description
The LM2480 driver is an Integrated 80V 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.
