LM2480 80V Triple Bias Clamp October 2001 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. n Single supply operation n Matched to the LM126X family of preamplifiers Recommended Applications n CRT monitors requiring DC restoration at the cathodes Features n Wide range integrated triple bias clamp n High input impedance Block Diagrams Package Pinout 20008302 FIGURE 2.
