Part Details:

LM2450 December 2005 220V LM2450220V Monolithic Triple Channel 7 MHz DC Coupled CRT Monolithic DTV DriverGeneral Description Features The LM2450 is a triple channel high voltage DC coupled n 7 MHz bandwidth CRT driver circuit designed for use in DTV applications. The n 100V black level adjustment range using 0V to 5V input IC contains three high input impedance, wide band amplifi- n Current output for IK feedback systems ers which directly drive the RGB cathodes of a CRT. Each T n Greater than 130V output swing capability P-P amplifier has a summing input where the DC level of the riple n 0V to 5V input voltage range output is controlled by a low voltage DC input voltage. Nor- n Stable with 0 pF­20 pF capacitive loads and inductive mally the DC input voltage is from a DAC. Each channel has peaking networks its gain internally set to -54 and can drive CRT capacitive Channel loads as well as resistive loads present in other applications, n Convenient TO-247 staggered thin lead package style limited only by the package s power dissipation. Applications The IC is packaged in a 15-lead TO-247 molded plasticpower package designed specifically to meet high voltage n DC coupled DTV applications using the 480p format as spacing requirements.
