TDA4865J; TDA4865AJ
Vertical de鏗俥ction booster
Rev. 02 鈥?3 November 2006
Product data sheet
1. General description
The TDA4865J and TDA4865AJ are de鏗俥ction boosters for use in vertical de鏗俥ction
systems for frame frequencies up to 200 Hz.
The TDA4865J needs a separate 鏗倅back supply voltage, so the supply voltages are
independently adjustable to optimize power consumption and 鏗倅back time.
For the TDA4865AJ the 鏗倅back supply voltage will be generated internally by doubling the
supply voltage and therefore a separate 鏗倅back supply voltage is not needed.
Both circuits provide differential input stages.
