Overview
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 means of the speed control pin.
The device can handle astigmatic, single Foucault and double Foucault detectors and is applicable with all N-sub lasers and N-sub or P-sub monitor diode units.
After a single initial adjustment the circuit keeps control over the laser diode current resulting in a constant light output power independent of ageing.
The chip is mounted in a small SO24 or TSSOP24 package enabling mounting close to the laser pick-up unit on the sledge.
