GENERAL DESCRIPTION

The TDA1300 is an integrated data amplifier and laser supply for three beam pick-up detectors applied in a wide range of mechanisms for Compact Disc (CD) and read only optical systems. It offers 6 amplifiers which amplify and filter the focus and radial diode signals adequately and provides an equalized RF signal for single or double speed mode which can be switched by means of the speed control pin.

FEATURES

• Six input buffer amplifiers with low-pass filtering with virtually no offset

• HF data amplifier with a high or low gain mode

• Two built-in equalizers for single or double speed mode ensuring high playability in both modes

• Full automatic laser control including stabilization and an on/off switch and containing a separate supply VDDL for power reduction

• Applicable with N-sub laser with N-sub or P-sub monitor diode

• Adjustable laser bandwidth and laser switch-on current slope

• Protection circuit preventing laser damage due to supply voltage dip

• Optimized interconnect between pick-up detector and TDA1301

• Wide supply voltage range

• Wide temperature range

• Low power consumption.
