Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that

Monolithic Linear IC
B/W TV Synchronization, Deflection Circuit
Ordering number:ENN857C
LA7806
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Overview
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.
Functions
• Synchro separator. • Horizontal oscillator.
• Horizontal AFC. • Vertical oscillator.
• Vertical driver. • Vertical blanking pulse making.
Features
• 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 warming-up drift.
• 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.

Sample Application Circuit
LA7806
Note) 1. The vertical output circuit is shown by the basic circuit.
2. The peripheral parts at pin 8 should be changed in accordance with the Ver. Out circuit conditions.
3. The limiting resistor (220Ω : 1Vp-p) at pin 14 should be changed in proportion to the magnitude of the input
video signal.
4. In the time constant circuit (120kΩ, 4.7µF) at pin 14, the time constant should be changed by changing the
resistance value in accordance with the DC level of the input video signal and then by changing the capacitance value.
