LM2423
220V Monolithic Triple Channel 15 MHz CRT DTV Driver
General Description
The LM2423 is a triple channel high voltage CRT driver
circuit designed for use in DTV applications. The IC contains
three high input impedance, wide band amplifiers which
directly drive the RGB cathodes of a CRT. Each channel has
its gain internally set to −54 and can drive CRT capacitive
loads as well as resistive loads present in other applications,
limited only by the package’s power dissipation.
The IC is packaged in an industry standard 11-lead TO-220
molded plastic power package designed specifically to meet
high voltage spacing requirements. See Thermal Consider-
ations section.
n Up to 170VPP output swing with AC coupling to
cathodes
n 0V to 5V input voltage range
n Stable with 0 pF–20 pF capacitive loads and inductive
peaking networks
n Convenient TO-220 staggered thin lead package style
Applications
n AC coupled DTV applications using the 480p format as
well as standard NTSC and PAL formats.
Features
n 15 MHz bandwidth at 130VPP output swing

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2: Operating ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and
test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may change when the device is not operated under the listed test
conditions.
Note 3: All voltages are measured with respect to GND, unless otherwise specified.
Note 4: Calculated value from Voltage Gain test on each channel.
Note 5: Linearity Error is the variation in DC gain from VIN = 1.15V to VIN = 4.35V.
Note 6: Input from signal generator: tr, tf < 1 ns.
