SANYO LA9511W

Ordering number : ENN6468
Monolithic Linear IC
LA9511W
AV Remote Coupler Transmitter
Overview
The LA9511W is a transmitter IC developed for freespace infrared transmission of stereo audio and video
signals. It integrates all the required functions for
transmission, including audio signal modulation, video
signal modulation, LED drive, and other functions on a
single chip. An AV coupler system can be implemented
easily using this IC and a receiver IC (such as the
LA9520V).
Functions
• Video preemphasis
• Video VCO. f0 adjustment from an externally applied
voltage: supports an electronic variable resistor function.
• Filter. Removes unneeded high-frequency components.
[Driver Block]
• Mixer and driver amplifier. Features excellent highfrequency characteristics and allows addition of external
data (remote control).

characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
