Texas Instruments LM2476
The LM2476 is a monolithic triple channel CRT driver and triple bias clamp for low-cost color monitor applications. The highly integrated IC contains three wide-band amplifiers for driving the RGB cathodes of a CRT through external coupling capacitors and three low-band clamp amplifiers for DC restoration and cutoff adjustment of the video outputs. The CRT drivers have a high, fixed gain of -27 and can drive CRT capacitive loads as well as resistive loads present in other applications, limited only by the package's power dissipation.| Part No. | LM2476 |
