GENERAL DESCRIPTION
The TZA1027 is an analog current buffer IC for CD-R and CD-RW systems with a 3-spot push-pull tracking system. The IC interfaces directly to the photo diodes and TZA1020. A HF current amplifier is implemented to detect the actual HF data signal.

FEATURES
• Eight amplifiers for servo and power calibration functions
• Gain selector for CD-R and CD-RW discs
• Separate data amplifier for read speed up to thirty times nominal data speed.
