LM2462TA/NOPB

Overview

The LM2462TA/NOPB is a monolithic triple high-voltage CRT driver designed for color monitor applications. It integrates three high input impedance, wide band amplifiers that directly drive RGB cathodes with an internally set gain of -20. The device operates on +80V and +12V supplies, supporting pixel clock frequencies up to 230 MHz. It features stable performance with capacitive loads up to 20 pF and inductive peaking networks. The component utilizes an industry-standard 11-lead TO-220 molded plastic power package.

Feature Summary

• Integrates three high input impedance, wide band amplifiers for direct RGB cathode driving
• Maintains standard LM240X family pinout for simplified PCB layout
• Stable operation with capacitive loads up to 20 pF and inductive peaking networks
• Higher gain configuration compatible with LM126X CMOS preamplifiers

Applications

• 1600 x 1200 displays up to 85Hz refresh rate
• Monitors utilizing video blanking
• High resolution display applications requiring pixel clock frequencies up to 230 MHz

Procurement Notes

Verify the specific ordering suffix TA against the manufacturer's current documentation to confirm package type and lead configuration. Confirm RoHS compliance status as indicated by the NOPB suffix in official datasheets. Ensure thermal management requirements are met, as the device requires a heat sink to maintain case temperature below 100°C during operation.

Selection Notes

Select this component for high-end CRT monitor designs targeting resolutions up to 1600 x 1200. Ensure the design accommodates the required +80V and +12V supply rails. Verify that the application circuit includes necessary arc protection components, such as fast transient response diodes and inductors, to safeguard the output stage from CRT arcing events.

Part Context

The LM2462 belongs to the LM246X family of monolithic triple CRT drivers. It is designed to work in conjunction with LM126X video preamplifiers and LM2479/2480 bias clamps to form a complete video channel from monitor input to CRT cathode. The device maintains compatibility with the standard LM240X family pinout to facilitate easy printed circuit board layout.

Replacement Considerations

Refer to other members of the LM246X family datasheets if alternative specifications are required. Verify pinout compatibility when substituting with other devices in the LM240X family.
