... AC coupling with DC restore, – DC coupling with Feed-back from Cathodes, – DC coupling with Cut-Off controls of the Video amplifier (ST Amplifiers TDA9533/9530). As for any ST Video pre-amplifier, the TDA9207 is able to drive a real load without any external inter- face. One of the main advantages of ST devices is their ...

... DC 4.7 Drive Adjustment ( bits) In order to adjust the white balance, the TDA9207 offers the possibility of adjusting separately the overall gain of each channel thanks to the I (Registers 3, 4 and 5). The very large drive adjustment range (48 dB) al- lows different standards or custom color tempera- tures ...

... Register 9 must be set to 1. 4.11.4 DC Coupling with feedback mode (Fig this mode, the feedback voltage issued from the cathode is sent to the TDA9207. This voltage is compared to a reference from the cut-off DC level DAC by the sample and hold circuit who also con- trols the DC voltage of the feedback input in a range of 0 ...
