philips TDA1300T TDA1300TT Photodetector amplifiers laser supplies handbook

TDA1300T and TDA1300TT are two integrated data amplifiers and laser power supplies that are suitable for a wide range of Compact Disc (CD) mechanisms and read only optical systems. The TDA1300T provides six amplifiers that can adequately amplify and filter the focus and radial diode signals, and provide an equalized RF signal for single or double speed mode that can be switched by means of the speed control pin. The device can handle astigmatic lenses and non-circular photodiodes.
