TDA6106Q ( Video Output Amplifier )
(1) General Description
The TDA6106Q is a monolithic video output amplifier (5MHz bandwidth) in a SIL 9 MPpackage, using high-voltage
DMOS technology, and is intended to drive the cathode of CRT directly .
To obtain maximum performance, the amplifier should be used with black-current control.
(2) Feature
• Black - current measurement output for automatic black current stabilization (ABS)
• Single supply voltage of 200V
• Internal protection against positive appearing CRT flash-over discharge
• Protection against ESD
• Internal 2.5V reference circuit
• Controllable switch-off behavior
