INTEGRATED CIRCUITS DATA SHEET TDA1300T; TDA1300TT Photodetector amplifiers and laser supplies Preliminary specification Supersedes data of 1995 Nov 16 File under Integrated Circuits, IC01 1997 Jul 15 Philips Semiconductors Preliminary specification Photodetector amplifiers and laser supplies 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. QUICK REFERENCE DATA SYMBOL VDD Gd(n) IO(d) B PARAMETER supply voltage CONDITIONS TDA1300T; TDA1300TT 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 me...
