TDA4881 Overview
TDA4881 The TDA4881 is a monolithic integrated RGB amplifier for colour monitor systems with super VGA performance, intended for DC or AC coupling of the colour signals to the cathodes of the CRT. With special advantages the circuit can be used in conjunction with the TDA4851. 8.8 56 1.0 − − 100 − − +2 +3 +240 +70 UNIT V mA V V mA mA MHz dB dB dB mV °C ORDERING INFORMATION EXTENDED TYPE NUMBER TDA4881 Note.
TDA4881 Key Features
- Fully DC controllable
- 3 separate video channels
- Input black level clamping
- White level adjustment for 2 channels only
- Brightness control with correct grey scale tracking
- Contrast control for all 3 channels simultaneously
- Cathode feedback to internal reference for cut-off control, which allows unstabilized video supply voltage
- Current outputs for RGB signal currents
- RGB voltage outputs to external peaking circuits
- Blanking and switch-off input for screen protection
