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.
The document is a preliminary specification datasheet for the Philips TDA1300T and TDA1300TT, which are integrated photodetector amplifiers and laser supplies. These devices are designed for use in Compact Disc (CD) and read-only optical mechanisms.
The circuit features six input buffer amplifiers with low-pass filtering to handle focus and radial diode signals, providing an equalized RF signal. It includes full automatic laser control with stabilization, mode switching, and a separate supply for power reduction. The chip is available in S024 or TSSOP24 packages.
