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 LM126/x family of pre-
amplifiers. Each amplifier has its gain internally set
to –18. The IC is package.
