LA9520V

Ordering number : ENN6469A Monolithic Linear IC LA9520V AV Coupler Receiver Overview The LA9520V is a receiver IC developed for free-space infrared transmission of stereo audio and video signals. It integrates all the required functions for reception, including I/V conversion for the received signal, a preamplifier, ALC, audio signal demodulation, and video signal demodulation functions, on a single chip. An AV coupler system can be implemented easily using this IC and a transmitter IC (such as the LA9511W or LA9512W). Video demodulator Video amplifier: Supports 75 Ω drive. Adjustable output level: supports an electronic volume control. Muting function: Mutes the output stage when there is no input signal. The muting function operating level can be adjusted from an input pin. Filter: Removes unneeded high-frequency components.
