Preliminary specification
Analog current buffer for CD-R and CD-RW
systems
TZA1027
FUNCTIONAL DESCRIPTION
All detector signals are applied to wide-band amplifiers for servo and laser power calibration functions of the TZA1020.
Signals from the central detector are added and amplified to suitable levels for the decoder circuit. Current gain can be
selected for CD-R and CD-RW discs.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
