LM2480 Datasheet | National Semiconductor

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 Remended 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 FIGURE 2.
