LA7806
Overview
Features
Functions
Ordering number : EN857D
The LA7806 is a multifunctional integrated circuit which is based on the internal circuit of the LA7800, incorporates
various functions required for synchronization and deflection circuits of monochromatic television set, and operates on
line voltage or from battery. This IC was so designed as to streamline the set by making the device more compact (DIP-16)
and reducing the number of parts.
The LA7806 differs from the LA7800 in the following points.
• No X-ray protection circuit is used.
• The ground pins for horizontal and vertical are provided separately.
• No horizontal regulator is used.
• Synchronizing separation output is for vertical only.
• Multifunction and small-size (DIP-16)
• Minimum number of parts required
• Horizontal and vertical oscillators being stable to variation of ambient temperature and supply voltage owing to small
• Small variation of horizontal oscillation frequency
• Good linearity and interlace owing to DC bias at vertical output stage being sampling controlled within retrace time
• Vertical blanking pulse width being freely set up according to peripheral parts
• Synchro separator
• Horizontal AFC
• Vertical driver
