TDA6111Q/N4,112

Video Amps And Modules Overview

The TDA6111Q/N4,112 is a video output amplifier designed to drive the cathode of a color CRT. It features a 16 MHz bandwidth and high slew rate. The device utilizes high-voltage DMOS technology and is housed in a DBS9MPF plastic DIL-bent-SIL medium power package with a fin (SOT111-1). Key electrical parameters include a high-level supply voltage (VDDH) range of 0 to 250 V and a low-level supply voltage (VDDL) range of 0 to 14 V. Quiescent currents are specified as 7.0 to 11.0 mA for VDDH and 5.0 to 8.0 mA for VDDL. The operating ambient temperature spans from -20 °C to +65 °C.

Video Amps And Modules Feature Summary

• Provides two distinct cathode outputs: one dedicated to DC currents and another for transient currents.
• Includes a feedback output that is electrically separated from the cathode outputs.
• Features internal protection mechanisms against positive Cathode-Ray Tube flashover discharges.
• Offers a black-current measurement output specifically for Automatic Black-current Stabilization.

Video Amps And Modules Applications

• Driving the cathode of a color CRT
• Integration with various colour decoders

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm the manufacturer origin aligns with current NXP Semiconductors standards. Ensure the component meets the necessary quality specifications outlined in the SNW-FQ-611 part E document. Check for compliance with relevant environmental directives applicable to the deployment region.

Video Amps And Modules Selection Notes

Select this component for applications requiring a single-chip solution to drive color CRT cathodes. Consider the thermal resistance requirements, as an external heatsink is mandatory due to the package's thermal characteristics. Evaluate the input bias and offset current specifications against the precision requirements of the connected colour decoder circuitry.
