• Manufacturer Part Number: cxa2568m
• Description: Rf Amplifier For Cd Players
• Manufacturer: Sony Electronics

Tracking Error Amplifier
resistor which determines the gain. The signal is amplified by the gain amplifier, operated by the tracking error
amplifier and then the (F-E) signal is output to Pin 13.
Each signal current from the photodiodes E and F is I-V converted and input to Pins 10 and 11 via an input
Pin 23 can be used as a bias for LC when connected to V
